Disclaimer: I do not own Transformers. Everything recognizable belongs to someone else. All I own is Lyra and Noah Montez.

Author's Note: I know that a lot of people have done a lot of fics where a TransFan gets sucked into the fandom, but my story is a little different. I hope you enjoy it.

Solemnly Swear

Prologue

"I, Lyra Montez, do solemnly swear…"

The shrieks of a young boy filled the air of the cold night. His sandy hair was in mishap, face coated with dirt and grime. He desperately tried to wake his unconscious sister. Her brown hair was splayed around her head, a tangled mess, and her chest rose and fell in fast, shallow pants.

"Ly! Ly, please, get up! Get up, Ly! I need you!" the boy cried, shaking the brunette's shoulders vigorously.

"…that, as long as I live, I…"

The ground shook as a large robotic sentient being advanced towards the siblings. Its red optics zeroed in on the crying boy, a sinister smirk pulling at its face plates. This was much too easy for the alien.

"Lyra, please wake up! We need to go, so…so…so wake up! Wake up or I'll tell dad on you!" the boy whimpered.

"Noah…?" The name was weak and barely audible above the destruction and chaos around them, but it was enough to calm the boy, Noah, if only for a second.

"…shall do everything in my power…"

"Lyra! Hurry up, you have to get up!" Noah yelled, fruitlessly trying to pull his elder sister off the floor.

"Wha-? Wha's goin' on?" Lyra asked groggily. She blinked, trying to focus on the chaos around them.

"…to keep you, Noah Montez, safe…"

Lyra's eyes landed on the robot, locking onto his red optics. Her eyes widened as she took in how close he was to them; he could cover the distance in five steps. She whipped her head around to look at the shaking form of her younger brother and finally registered what was going.

"You gotta run, Noah," she said, painfully pushing herself up into a sitting position. The action left her gasping for air and whimpering in pain.

"No! Not without you! Not without you…" Noah objected, tugging at her hand weakly.

"I-I can't, kiddo. I hurt. You have to go without me. The Decepticons, they don't want me, they want you. That's why they took you, because you have information they want," Lyra wheezed out, removing her brother's grip from her arm and giving him a gentle push. "You're the one who knows Transformers, No', so you gotta go. Find Prime, he'll know who you are."

"I'm not leaving witho—"

"Damn it, Noah! Get out of here!" Hazel eyes flashing with anger, she shoved him away with as much strength as she could muster. He stumbled a few steps back, but didn't fall over. After all, 'all her strength' wasn't really all that much.

"…even if it costs me my life, and…"

Noah didn't want to leave, but he was still in shock from the fact that Lyra had pushed him to fight back. Instead, he stumbled away, taking the Decepticons attention with him.

"You think you can run, fleshling?" the 'Con laughed, taking a step towards the now running boy.

Lyra saw this and was fueled by a new power, the motivation to protect Noah. Looking around her, she spotted nothing of use but a pile of rocks a ways away. Struggling to her feet, she painfully limped towards them wondering how, in this chaos, not a single piece of rubble had managed to land near her.

Bending to pick it up was the hard part. The ground shook with every step the Cybertronian took, hindering her balance far more than her injuries did. Lyra nearly toppled over with the strain of grabbing a rather large rock, but she managed to stay on her feet. Whipping around as quickly as was possible without causing too much pain to herself, she lifted her arm up, aiming for the large metal being that dared to hurt her brother. It took every ounce of energy, every fiber of her muscles, to throw it.

Lyra watched, holding her breath unconsciously as she collapsed to the floor. It soared in the sky for endless moments, flying towards its mark until it finally hit it. There was a dull 'clink' that seemed to resonate through the raging city as the transformer was hit on the head by a piece of broken cement. He turned slowly, as if dumbfounded, and focused his optics on the brunette.

"Come and get me, you pile of scrap metal," Lyra whispered, not having enough energy to speak any louder. But the 'Con heard her, and he was furious.

Who was she to insult him? An organic bag of flesh, bones, and slimy organs? Raising his canon, he charged it up, the ominous hum sending a wave of acceptance crashing onto Lyra. She shut her eyes, tilting her head downward. The action confused the 'Con, but he didn't pay it any mind. Instead, he focused on how easy it was to kill humans, how their guts splatter everywhere.

"I love you, Noah," she whispered, a single tear falling as she realized that it was over; she would die in Mission City.

"…may Primus be my witness."
