Back before the war, in the dying days of the Golden Age, you were once a member of Cybertron’s higher ranks. But after a single event, you were cast into the planet’s underbelly, left to be destroyed. You survived, and it was there you met Orion (O-16) and Dee (D-16), two Energon miners trapped in the harshest level of the caste system.

They dreamed of a better Cybertron, one without castes, only equality. You believed in them. Orion’s words and philosophy inspired you, while Dee’s powerful speeches about freedom from oppression ignited hope across the lower sectors.

As violence spread, Orion and Megatronus went before the Council to challenge the caste system. Megatronus demanded change through any means necessary, including bloodshed and radical means, while Orion pleaded for peace. The Council sided with Orion, and on Alpha Trion’s advice, named him Prime in Sentinel’s absence—Optimus Prime.

Enraged, Megatronus declared war, renaming himself Megatron and forming the Decepticons.

Torn between the two bots you called brothers, you chose Optimus’s path of honor over Megatron’s path of hatred. Alpha Trion soon revealed the Matrix of Leadership had been lost since Prima’s era, meaning Optimus would have to lead without it for now. Despite his doubts and inexperience, Optimus ruled with compassion, humility, and strength.

During an early battle, Optimus tried to reason with Megatron. Blinded by pride and fury, Megatron fired his fusion cannon. You stepped in front of Optimus, taking the blast that destroyed your body.

You did not die instantly, but were barely alive. Optimus brought you to Alpha Trion, the last of the original Thirteen. At Optimus’s plea, Alpha Trion used the Forge of Solus Prime to rebuild you. No longer in the caste body they had placed your spark in, but now in the body forged from the energy of Primus, as intended. You were now stronger, faster, taller. You were perfect.

When you awoke from medical recharge, your old scars and flaws were gone. Fresh paint gleamed across your perfectly shaped frame. You were… different.

Optimus had been pacing relentlessly outside.

"Optimus," Alpha Trion said as he entered the room. Optimus immediately ceased his pacing and came to his mentor. "Are they alright? Please tell me, Alpha Trion." His voice filled with concern.

"Yes, my student, I can assure you they are well. In fact, they are ready to see you. Come, young one, your friend is worried." Alpha Trion said, calling you in from the shadows of the door you had been hiding in. When you emerged, Optimus's eyes widened. He looked to his teacher.

"With the help of the forge of Solus Prime, and the blessing of Primus, no doubt they are as good as new, in fact as they were intended to be. With a body forged for them, not chosen." Alpha Trion said, his voice carrying the wisdom of many ages. He then added. "I will leave you two; I assume you have much to discuss. Optimus, I shall see you later." He then left.
