After conversing with Sindri, Hulk resumes to head towards the mountain alongside Kratos and Atreus. As they head up towards their destination, three hooded hag-like figures appear out of nowhere, who cackle at the trio of heroes.

"What are those things?" Hulk asked as he got into a fighting stance.

"Mother told me about these. They're Revenant. Witches without souls after they used bad magic!" Atreus called out to Hulk, who started swinging his massive arms at them, but it was like they were made out of wind; his attacks weren't hurting them at all.

"Grr! Stop doing that!" Hulk roared in frustration as he continues to punch at the Revenant, still not harming them.

"Brainless beast..." Kratos thought to himself as he watched Hulk struggle with battling the Revenant. Suddenly, Hulk, frustrated by the Revenant cackling at his inability to hurt them, clapped his hands together, which released a devastating shockwave, dazing the creatures. Hulk punched one of the Revenant into a rock wall, killing it while Kratos swung his axe at the second one's neck, beheading it. As for the third one, Hulk unleashed another thunderclap and repeatedly slammed the creature's head against the rock wall, caving its skull in until nothing was left, dropping the headless corpse to the ground.

"Whoa! That was so cool!" Atreus exclaimed at the brutality that he had just witnessed.

"That...was annoying..." Hulk grumbled as he stomps on the third Revenant's remains.

"How'd you know that...clap thing would work on the Revenant?" Atreus asked as the three resume walking up towards the mountain.

"There was a villain from my world. Vapor. She's a crazy lady made out of poisonous gases. I clap at her, make her weak, then I can beat her." Hulk said as Atreus walks alongside him.

"Wow. Your world sounds weird...but cool." Atreus replied softly.

"Grr..." Kratos mumbled to himself.

-Later-

A few minutes pass as the three arrive at a ruin of some kind, with a large piece of rubble blocking the door. As Kratos starts to move it, a creature with and ape-like stance bursts through the door, its mouth hanging open as it charges towards Atreus and knocks Hulk over a ledge of the cliff, though Hulk grabs the side of the cliff and starts climbing as the creature focuses on Atreus again, though when it lunges, it bites down on Kratos' arm.

"Grr! Jerk..." Hulk mumbled as he climbs back up. "What is that?" Hulk asked as he looks at the creature.

"It's an Ogre!" Atreus shouts as he stabs the grotesque beast in the eye, making it release Kratos' arm from its mouth.

"Ugly..." Hulk grumbled as he pushes the Ogre against a pillar and punches it several more times, dazing it before slowly applying literal bone crushing pressure to its skull, shattering it and killing the monster. "You alright?" He asked both Kratos and Atreus, though it was mostly aimed at Kratos since the Ogre was biting down on his arm for a while.

"It is nothing." Kratos grumbled. "We must move on."

(Later)

After that, the trio head further up the mountain's path, coming across a mountain with a carved face before noticing a strange, black mist blocking their path. As Atreus approached the fog, he recoiled from it and covered his face. "Ugh...what is that?" The boy asked with a groan in his voice.

"No clue..." Hulk replied, having never seen anything like this on his world. "Bet it's gonna be a problem, though."

"We must find another way up." Kratos said blankly as he looked at the mist.

"And how will we do that, old man?" Hulk inquired as he looked at Kratos and crossed his arms.

Atreus smiles softly, getting an idea on how to get through. "The Witch! Wish she was here right now. I bet she could get us past this...whatever it is."

Almost right on cue, the Witch appeared spontaneously out of nowhere, walking up behind them and says, "My magic is useless against the Black Breath. There is also no way around it. Odin himself saw to that a long time ago." She said as Atreus jogs over to her, happy to see her again.

"What are you doing here?" The boy asked.

"Making sure you and your friends can finish your journey." The Witch replied, putting her hand on Atreus' shoulder.

"Wait. If you knew that this...'Black Breath' was here, why didn't you tell us?" Hulk asked in bewilderment.

"For once, I must ask the same." Kratos adds to the question.

"I was busy. Saving my friend if you remember." The Witch replies in a smartass way.

"Your pig friend was already healed, dummy. You could've told us this at any time." Hulk said, not buying that she couldn't have told them about the Black Breath.

For once, the Witch had no remark to that and simply said, "Black Breath is a corruption of magic that even I can't dispel. The only thing that is strong enough to break through it...is the pure Light of Alfheim. But that is a long road. What does your journey mean to you and your boy?" The Witch asks Kratos.

"It's everything..." Atreus replied softly, prompting the Witch to look down at the boy.

The Witch nods slightly in understanding then looks at Hulk and Kratos. "Alright. Follow me."

However, Kratos roughly grabbed her arm, stopping her. Like Hulk, he didn't trust her in the slightest. "Why? Why help us?"

The Witch pulls her arm away and looks at Kratos. "Perhaps I see more of myself in you than I'm willing to admit. Maybe...Maybe if I help you, it'll make up for my lifetime of mistakes..."

"Where do we have to go to get this 'Light'?" Hulk asked the Witch.

The Witch looks at Hulk. "To a realm beyond this one."

"I can't believe it. We're going to another realm!" Atreus exclaimed to himself excitedly as the trio, plus The Witch got an a large lift of some kind that led down the mountain to where they met Sindri.

"Tyr's Temple is at the center of the Lake of Nine. From there, we will travel to Alfheim. To our good fortune, it is no longer underwater." The Witch says.

"Why is that beast in the bay?" Kratos asked, referring to Jormungand'r.

"Nobody really knows; he just appeared one day. Soon after, Thor attacked him...and their brutal battle could be felt across all the realms. The brawl ended in a stalemate, and Thor returned to his father empty-handed. The Serpent stayed in the Lake and grew so large that he now spans over all of Midgard." The Witch said as the lift finally reached the ground, but Sindri was nowhere in sight.

(Later)

The group enter a cavern, where the Witch reveals she has access to a small amount of the Light of Alfheim, which she applied to her bowstring, allowing them to press onward to Tyr's Temple, though they had to make a detour to fix the mechanism on the bridge; one of its axles was off balance, though Hulk set the axle back in place, then, much to the amazement of both Atreus and the Witch, effortlessly pushed the bridge into place so they could travel to Alfheim.

"Wow! You're really strong!" Atreus exclaimed after witnessing Hulk's remarkable strength in action again.

"Really strong is putting it mildly..." Hulk remarked as the group entered the Temple.

"Will you come with us to Alfheim?" Atreus asked the Witch.

"I cannot step foot in Alfheim for more than a few moments. Odin took measures to keep me on Midgard." She said in answer.

"Why?" Hulk asked.

The Witch answered with, "The gods here do not like me very much."

(Realm Travel Room)

The group enters a dark room, coming across a tree sitting in the middle of the room, though the top half was inexplicably hovering in midair as some large roots formed together into a bridge so the trio, plus the Witch could get closer.

"Those roots don't look like your magic." Atreus said as he looks at the large roots on the floor then looks back at the Witch.

"That's because they aren't." The Witch says to Atreus. "These roots...They are part of the great World Tree, which is what makes travel between the realms possible."

"Mmm..."Hulk grunted lowly as he looked at the tree.

"How does it work?" Kratos asked the Witch, who held a key-like object in front of him.

"Here. You will need this. A Bifröst-A key that will allow you to travel between realms. It can capture, hold, and transfer the Light of Alfheim." The Witch said before handing the object to Kratos. "Place the Bifröst into the slot on the machine." Kratos does just that, gently inserting the Bifröst into the contraption that was surrounded by the World Tree. A small statue emerged from the machine as it glowed a bright, ethereal blue. "The statue you see resembles the temple we stand in, as well as the realm towers that encircle the Lake outside. All the realms exist in the same physical space, reflections of one another. The doors, the towers, and the realms themselves are all intertwined; coexisting on the branches of the World Tree-separated only by the Bifröst light of Alfheim, Land of the Elves. The bridge that your green friend moved is currently positioned to lead to Vanaheim. Instead, you want the bridge to be pointed towards Alfheim. Each realm requires a magical rune to gain access to it." The Witch says as she makes a magical rune appear on Kratos and Hulk's palms. "This is the rune to Alfheim."

-Alfheim-

After turning the wheel on the machine, the World Tree activates and transports everyone present to Alfheim. Once outside, the area looks like an exotic forest that you'd hear about in a fantasy novel, with plants and greenery all over. Even Hulk thought to himself that Alfheim was a beautiful place.

"Welcome to Alfheim." The Witch said in a welcoming tone before noticing that the Light of Alfheim wasn't visible. "The Light...I can't see it. Something is wrong. Wait. That light on the horizon. It's a temple that the Light is held in." Before the Witch could continue on, she became enveloped in a white light as a portal opened behind her and began to pull her away, though Kratos and Hulk quickly grabbed her hands to keep her away from the portal. "There isn't time! To restore the Bifröst's magic, one of you must step into the Light! But you mustn't get caught up in-" The Witch quickly said before she was pulled back into the portal despite Hulk's best efforts.

"No!" Atreus yelled in protest. "Where'd she go?"

"Do you think she's dead?" Hulk asked as he crosses his arms.

"Not likely." Kratos said blankly. "Come."

"You really think she would've told us about the Light before getting sucked out. Geez, this woman is thick headed!" Hulk says in his head, groaning at the Witch's apparent stupidity.

As the three walk down a long bridge, Atreus spots some Nordic runes which read out, "An eternal war for the Light". Before any of them could question it, they saw a person in a glowing robe being stabbed by a strange creature with a triple-pronged spear. The killer was a Dark Elf, and several more of them flew in and attacked the trio upon spotting them, though Hulk and Kratos quickly dealt with them, punching and hacking at them until they were in literal pieces.

"These are Dark Elves." Atreus said, having heard stories about them from his late mother. Before anything else could be said, Atreus could swear he heard someone say something and looked at Kratos. "Did you say something?"

"I did not." Kratos answered.

The three kept moving, hearing the faint sound of a smithing hammer hitting steel.

"Hear something?" Hulk asked.

"Wait. Is that Sindri?" Atreus asked, recognizing the noise. As they walked towards the noise, it got louder and more clear until they saw Sindri. Somehow he had gotten to Alfheim before they did.

Upon reaching Sindri's worktable, Kratos got right to the point, asking, "How are you here before us, Dwarf? We were told our path was the only one between the realms."

"Heh. It might be the only way for you people to travel, but Dwarves are full of many surprises." Sindri says, which didn't exactly answer Kratos' inquiry.

"That is not an answer to my question." Kratos said impatiently.

"Now, now, just hold on to your sense of wonder." Sindri said waringly.

"Why should we?" Hulk asked, his arms crossed on his chest.

"Well...because there's so little mystery left once you've amassed the amount of arcane knowledge like me."

"Whatever, midget." Hulk remarked.

"I am no midget! I am a Dwarf!" Sindri shouted at Hulk rather defensively.

(Later)

After finding a canoe to row down the river, Hulk shifted back to Bruce Banner so he could accompany Kratos and Atreus; otherwise the canoe would explode into numerous pieces under his weight.

As Kratos started rowing after Bruce and Atreus got in, he looked at Atreus and asked, "What did your mother tell you about this realm?"

"She didn't tell me much." Atreus answered with a shrug. "She just told me that since the Elves were always fighting over the Light, it kept them isolated from each other."

"They shouldn't be fighting for such greedy reasons..." Bruce thought to himself after hearing this, though he was interrupted as Atreus had a confused look on his face; he was hearing voices in his head again.

"Huh?" Atreus asked out loud, unsure as to the origin of the voices as he looked to Kratos.

"Again...neither I nor the man said nothing." Kratos said to the boy as he kept rowing.

"Weird. I could've sworn I heard-AGGGHH!" Atreus began to say, only to clutch his head in pain and scream.

"Atreus!" Bruce shouted with concern as Kratos tended to Atreus.

"Boy. What is wrong?" Kratos asked with care.

"Voices...Arggh...You two don't hear them?" The boy asked with a groaning tone.

"No. We heard nothing." Kratos answered.

Atreus groaned more before the pain in his head subsided. "I heard screaming. Lots of angry voices." He said, feeling pain and loss of life from just the voices in his mind as Kratos resumed rowing the canoe, passing by numerous dead bodies of Light Elves.

They eventually arrive at a large, wide lake, very similar to the one on Midgard. Kratos docks the canoe and the three get out, coming across a sand bowl, in which Atreus noticed had a symbol on it.

"What does it ask?" Kratos asks the boy.

"It says...'Without me or within me, death is sure. Yet within you, I am life lost pure.' Weird. I don't see any runes around to read."

"Rrr...We must find it." Kratos grumbled in frustration. "Back to the boat."

The three board the canoe and row towards the ringed temple that the Witch told them about, spotting a shiny blue door in the distance. However, before they could even begin to cross the bridge of light that would lead them there, some strange tentacles wrapped around the light crystal, making the bridge disappear as some Dark Elves fly over, hovering above the trio. The Dark Elves continually dive downwards and stab at the three strangers with their spear-like weapons. Bruce panics as he tries to dodge the swift attacks, but is eventually stabbed in the leg, screaming in pain as blood spurts from his flesh wound. However, he feels Hulk starting to emerge as the muscles in his leg start to enlarge. He then looks at the Dark Elf that stabbed him and grins darkly before pushing the weapon out of his leg, which then heals within seconds.

"You shouldn't have done that...because you've made me angry!" Bruce said as he transforms back into Hulk and punches the Dark Elf away.

"Wow..." Atreus said in awe as Hulk punched and swatted several Dark Elves with his bare hands like they were nothing. Soon, no Dark Elves remained.

"Stupid..." Hulk muttered to himself before noticing two large crank wheels nearby.

"Hey, look!" Atreus said as he points at the two wheels. "Maybe we can use these to get the bridge back?"

Hulk shrugged and started to roll one of the wheels, making large curved structures emerge from the lake and make a formation of some kind. After stopping, more Dark Elves arrived, but Hulk and Kratos made short work of them and Kratos spun the other wheel. Atreus then noticed something: with the two structures formed together...they looked like a rune of some kind.

"Look! When those things combined like that...It looks like a rune of some kind." Atreus said as he looks at the ring-shaped structures protruding from the lake.

"Then let's see what it means..." Hulk said to Atreus before turning into Bruce again and he gets in the canoe after Kratos and Atreus do so.

Upon getting back to the sand bowl from before, Atreus focuses on the strange structure and says, "Wow, it looks like an Elvish rune!"

"What does it ask?" Kratos grumbled.

"Like it said before, father. 'Without me or within me, death is sure. Yet within you, I am life most pure'. Hold on..." Atreus said as his brain scrambles to find the answer before realizing what the answer was. "I got the answer. It's water." He added as he prepares to carve the rune into the sand bowl, only to bend over, clutching his head and screaming like before. The voices were back. "AGGGHH!"

"Atreus!" Bruce shouted with concern.

"The voices again...but they were different, less angry. They...were begging, asking for help." Atreus said, which sent a chill of horror down Bruce's spine.

"Well, if people are in trouble we should-" Bruce started to say before being cut off.

"No. We are here only for the Light. I do not care who those people are or what they want." Kratos said coldly, condemning the people Atreus heard to die.

"You never care about anything..." Atreus mumbled to himself, which Kratos heard.

"You have something to say?" Kratos asked as he took a step toward Atreus.

"No..." Atreus said almost immediately as he carves the Elvish rune into the sand bowl. The sands glowed as the lake started to open up, and the platform that the three were standing on was descending.

"Wow..." Bruce softly said to himself as the platform descended.

"Um...Father?" Atreus added, getting Kratos' attention, who looks down at the boy.

"Yes?" Kratos replied gruffly.

"The voices I heard...I...Well, it was kind of hard to make out...in the back of all the voices...I think I heard Mother." Atreus said sadly, in which Bruce looked at Atreus with a sympathetic expression.

"That is not possible." Kratos replied, not thinking that Atreus heard her. As the platform descended more, another Dark Elf appeared, but this one was different. He was more muscular, had thicker armor, large horns, and was carrying a strange looking glaive or staff-like weapon.

"Another Dark Elf! But it's different..." Atreus said as he observed the Dark Elf.

Things got bad when the platform stopped descending, and a group of Dark Elves attacked while the larger one observed from above, a shocked expression appearing on its face as it saw Bruce transform into Hulk, who made short work of his share of Dark Elves, beating them to death with his fists while Kratos cut through his own with his axe. Realizing he was outmatched, the bigger Dark Elf cowardly flew away.

"Coward!" Hulk roared as he punches his final Dark Elf.

(Later)

Minutes go by as the trio venture throughout Alfheim, slaughtering numerous groups and bundles of Dark Elves until making it to where the crystal for the light bridge was covered by those tendrils. As soon as they got there, Dark Elves flew in from above, but like before, they were no match for Kratos' rage and Hulk's brute strength. However, as soon as the Dark Elves were killed, a series of rocks shifted into a towering humanoid shape.

"Ahh! Stone Ancient!" Atreus hollered as the Ancient rose up and swung its right arm at the boy, but Hulk easily halted the attack with his left hand.

"No hitting kids." Hulk said before hitting the Ancient with his right fist, staggering the stone being quite a bit. Hulk then punched the Ancient again and again until it crumbled to a pile of rubble due to the growing intensity of his punches.

"Wow!" Atreus exclaimed. He was sure that he'd never get used to seeing how strong Hulk really was. It was like nothing could hurt him, let alone beat him in a fight.

Kratos spotted the source of the tentacle blocking the light bridge, using his axe to rapidly freeze it before hacking it in half with a single chop, making the tendril disintegrate and allowing the light bridge to reappear above the three. "The light bridge is back. But how are we gonna get up there?" Atreus asked, only for Hulk to grab both Atreus and Kratos and leap upwards, making the boy holler in surprise as Hulk landed on the light bridge.

"Do not ever...do that again..." Kratos grumbled as he yanked himself free of Hulk's grip. Even after all of this, he still didn't trust Hulk.

"Wimp." Hulk said to Kratos in a teasing way.

(Later)

The trio continue on, getting closer to the Light as they arrive at what appears to be a hive of some kind that the Dark Elves are living in. As they ventured further, the intensity of the Dark Elves got greater, though Kratos, Atreus and Hulk still managed to chop, shoot, and punch their way through the opposition, eventually reaching their destination: the Light of Alfheim. It was so beautiful, even Hulk was amazed by its intense glow.

"That's gotta be it." Hulk said as he approached the Light alongside Atreus, the latter of whom noticed that the usually dark area was beginning to light up again.

"Look. The temple...It's lighting up again!" Atreus said, observing light returning to Alfheim. As he reached out to touch it, Atreus recoiled his hand. "Ahh! That really hurt! It felt like my hand was on fire..."

"Boy...you and the beast stay here..." Kratos said as he stood in front of the Light before holding his axe in front of Atreus, who looks up at Kratos. "Only use this...as a last resort."

"You're...giving me your axe?" Atreus asked as he held the large weapon in his hands.

"I am letting you hold it. It is not a gift." Kratos said.

"Still...you never let me hold it before now..." Atreus softly said as he looks at the axe.

"Better come back, old man." Hulk said to Kratos in a teasing way.

"I do not plan on staying, brute." Kratos said as he pushes himself into the Light, screaming in pain as he does so. Like with Atreus, it hurt really bad when he touched the Light. Soon, Kratos' entire body was enveloped by the Light, then he was gone.

"Now what?" Hulk asked as he looked down at Atreus, unsure of what to do until Kratos returned. Atreus simply shrugged his shoulders as he kept gazing at Kratos' axe.
