I LOVE MY OCS!!! Lemme paste Mikhail's synopsis:

Summary: Dimitri and Byleth’s son and the lost prince of Faerghus. He was born a year after the war ended, but he was kidnapped by TWSITD not long after his birth. To add insult to injury, TWSITD faked Mikhail’s death by planting a fake corpse to mislead everyone.

TWSITD wanted to turn him into an indestructible superweapon, specifically, an artificial dragon, because he had both Nabatean blood and the blood of the strongest crest (Blaiddyd). For the time being, they modified his body in Shambala. Unfortunately, TWISTD’s plan was ultimately cut short 8 years later when the Blue Lions stormed into Shambhala and destroyed the compound, not knowing Mikhail was alive this whole time.

He survived the attack on Shambhala, and spent the next 16 years of his life wandering aimlessly around Fodlan, trying to survive on the streets and live off whatever he could. He discovered his potential in the sword and eventually found a somewhat stable living as a mercenary.

One day, while in the forests of Eastern Faerghus, he encounters a noblewoman named Ada, and from there on, his life takes a completely different turn.
