A/N: So this is in response to a challenge given out by my friend ChangingDestiny40! Oliver, Nyssa and Sara are somehow sent back in time to the pilot episode after failing to defeat Damian Dahrk, Vandal Savage and Zoom who have worked together to create a terrible future! They decide to use their knowledge of the future to make things better, including stopping Malcolm and Slade. Now, there are two important things that I need to say before we begin. First of all, this will be Nyssa/Sara/Oliver or Assassin Canarrow. I'm sorry to all of you Olicity shipper's, as I truly love her character, but in my opinion she is Oliver's Chloe Sullivan. A best friend, and an ally, but their romance has gone on far too long. Again, that's JUST MY OPINION. Secondly, this will be a crossover with Smallville and Flash eventually, but not for a while. Or maybe I should just say Smallville since Flash and Arrow exist in the same universe. Anyway, now that all that's out of the way...On with the show.

The Watchtower Headquarters of the Justice League- 2027

"Barry!" Oliver screamed as he saw his friend struck down by Zoom. Well, if the Emerald Archer was honest with himself, struck down was a polite way of putting it. Zoom had actually shoved his hand through Barry's spinal cord, rendering the fastest man alive unable to do anything other than fall to the ground. Oliver fired arrow after arrow at the monster who had made it his mission to destroy Barry's life, only for them to be halted in midair and sent back at the archer.

"Come now Oliver. You didn't think it would be that simple did you?" Damian Dahrk asked as Oliver dodged his own arrows. Across the room, Cisco screamed as he saw his wife Kendra lose her head to Vandal Savage's sword. Mind empty of any thought save revenge, the hero called Vibe charged the immortal, only to share his wife's fate. Oliver wanted to scream in rage, but even that was denied him as he felt one of his own arrows pierce his leg. However, even as he went down to one knee, the archer held his bow, an arrow aimed at Dhark.

Oliver's eyes narrowed in rage as he thought of the last time he had seen the leader of H.I.V.E. It had been the same day that he had watched Thea, Roy, Felicity, Laurel and Diggle die. That monster had come into his home and destroyed his family, while Oliver had been unable to do anything but watch helplessly. If they hadn't been away on a mission with Clark, Nyssa and Sara would have most likely died as well. The thought of all that Savage, Dhark and Zoom had taken from him and his friend's made Oliver do something that he had sworn to never do again. He fired his bow, with only one goal in mind. To kill Damian Dahrk.

The next thing he knew, he found himself in Superman's arctic fortress, looking into the blue-eyes of the Man of Steel.

"It's done then?" Oliver asked, and Clark nodded before walking over to where Nyssa and Sara waited.

"And you're sure you won't come with us?" Sara asked, and Clark shook his head.

"I'm needed here. If you should fail, someone has to be here to keep fighting." He replied, and the three nodded in understanding. The Last Son of Krypton handed each of the three a ring, which they slipped on their fingers.

"Oliver, if you could do one thing for me?" He asked, and Oliver nodded once.

"We will save her Clark. I promise you that."

"Thank you." He said, embracing his three friends before stepping back.

"Shall we?" Oliver asked, and the two women smiled.

"Indeed we shall beloved." Nyssa replied.

"Let's go." Sara said, and the three touched their rings, disappearing in a flash of light. The last thing they saw before Clark disappeared from their sight was Clark saying "Wonder twin power's activate!"

"Shouldn't it be wonder triplet's?" Oliver quipped, making Nyssa groan, while Sara just laughed.

"Oliver did we-"

"Yes we did Nyssa. Clark's plan worked. We're back." Oliver said as he looked out towards the sea. Clark's plan had indeed worked. The three were back on Lian Yu. They were once again in purgatory.

A/N: So, here we have it! The prologue of this story! Please tell me what you all think, and I will try to have a new chapter up soon!
