A/N: Finished this awesome game some time ago and I couldn't keep my mind from what ifs and what not. The artwork of both Byleth's standing looking up and surrounded by all the students gave me so many ideas. I just had to write them out.

This will be a Golden Deer centered fic but the Blue lions are also important.

Since Byleth is named after a demon I decided to give his sister a name after a demon as well. The name that I've given her is: Balaiya. One way or another it was taken from Belial.

~Let me know what you think.

Prologue: The Stone Faced Twins.

"Hey-up!...Bala... Get up... Balaiya wake up!"

With a heavy thump she hit the floor.

"O-ow…" Balaiya grunted and sat up slowly, a frown painted on her lips which only deepened on hearing the familiar tsk tsk from her older brother.

"I could have had your head on a pike by now Bala. What kind of wake up was that?"

Balaiya grunted once more and peered up through narrowed eyes. "Morning to you too Leth. I could ask of you the same thing, What kind of wake up was that anyway, Did you have to toss me from the bed?"

Byleth shook his head and crossed his arms with a frown. "You must always be alert. You never know when we'll get attacked." He tossed his sister's clothes to her and turned around.

Balaiya sighed and stood up, stretching till her bones cracked. She was going to be sore for a while, especially her jaw. Hitting the dirt like that wasn't fun. She'd definitely have to get him back somehow… but how?

"Father wanted me to get you, so you have two minutes to join us outside." Byleth said, a hint of impatience in his voice. He made for the exit of the tent.

"Yea, I'll be out as soo-" She sighed as the flap to her tent shut before she finished. Grumbling to herself she went about dressing herself. "Seems like being born seven hours early gives you a big head." She muttered to herself.

He'd always been like that, hovering over her. Making sure she was doing this and that. Much like their Father did. Of the two of them, their Father always assigned the more important duties to Byleth.

Determined to best the two minute mark her brother placed above her head she hurriedly slipped on her black leggings. Taking a moment to lament the loss of her tights, she knew they were not good for travel. She was just surprised her father and brother tolerated them so long. Though the glint of glee that shone in her brother's eyes when she got stuck to a torn bush was certainly his own equivalent to laughing in her face. The worst part? He had always done that. Laughing with his eyes, something that infuriated her because she could never get him into trouble for it!

After all, saying: My brother laughed at me. When in fact, he physically wasn't was a difficult argument to make. So, she had to develop her own ways to get back at him.

Once dressed she stepped outside and surveyed the area. Her father and brother stood a ways off chatting idly. 'I wonder if he had the same dream…' She thought. Ever since they were little, the same few dream had been reacurring between them. Often it was a battle, a large scale and bloody battle. Other times it was a girl. One that never spoke to them. This time it was a little different— she dreamt of the battle and the girl. Balaiya hurried over to the pair and cleared her throat. "Good morning father. I'm sorry I was late… I was-"

"Dreaming?" Byleth finished for her.

Balaiya turned her head towards her brother a slight gasp caught in her throat. 'So he did?...' She mimicked his stance, crossing her arms in front of her bound chest. Byleth glanced over to her and nodded, relief instantly spread through her. Once again they were on the same page, two sides of the same coin. Rarely did they simultaneously have the same dream, but when they did— that comforted her.

"What was the dream about Balaiya?" On hearing her name she turned her attention back to her father. Should she mention the whole thing? Or only parts of it?

Byleth shifted at her side and spoke first. "A battle."

She smiled inwardly and added. "One of great proportions... The one we've mentioned before."

"Huh, that one again. Well, one like that hasn't happened in many years. Are you sure it's not from something you read?"

Balaiya shook her head. "Not that I am aware of." They didn't read much to begin with. Being a mercenary required little allowance for such pleasantries. Besides, they'd been having the dream far longer than they admitted to their father.

Jeralt rubbed his chin in thought and gestured to the rest of their group. "I'm going to make sure everyone else is prepared to go. I'll see you two in a bit. Let me know if anything else happens."

She nodded, waiting until he was out of earshot before facing her brother. "The girl on the throne. She spoke to me this time."

His eyes widened when he looked at her, surprise evident to her. "Spoke? She didn't speak to me. Merely she did as she always does and simply sat in the chair asleep." He frowned slightly "Well, now that I think of it, she did look at me for awhile, but she went back to sleep." His voice lowered to a whisper though he kept his gaze set over her head, she did the same with his blindspots. One can never know when someone might be listening, and something told them to keep this to themselves."What did she say to you Bala?"

"She asked for my name and birthday."

"You told her?"

"I couldn't stop myself." No matter what she said or tried— dodging the question, or being ambiguous. It was as if she was compelled to answer.

Byleth sighed through his nose, unease seeping into his voice. "What if she's dangerous?"

"Even when I tried not to give a straight answer, it was as if I was given no other option. I can't explain it." She closed her eyes as she remembered the way the strange girl's eyes bore into her.

He sighed again, and dropped his arms to his side. "Do you feel threatened?"

She clenched her hands a few times and shifted in her stance. Threatened by the mysterious girl? No, but there was something in the air. Something unpleasant? Or was it just unease? She shook her head once. "No. Do you?"

"No. But if it happens again…"

She looked into his eyes then and knew, he certainly felt as uneasy as she did. "I will." She said.

He nodded and took a deep breath, a hand running through his hair. "Alright, we should catch up with Father."

Balaiya nodded and fell into step behind her brother, not before glancing over her shoulder.

She couldn't shake the feeling that something or someone was definitely watching them.
