StarPlague
His bio is not completely finished but long story short:
despite being an Arcane dragon, he was born under the blessing of the PlagueBringer, which... turned out to be more a curse than a blessing, really. It made other villagers fear him - they were terrified of the Plague that affects him since his birth. He was the only one affected by his plague though, so that treatment was not only unfair but also made absolutely no sense.
Soon he was chased away from the village, left to fend against beast clansmen & to starve alone.
Vengeful, he begged Plague Mother to turn his blessing into a powerful curse, to use against those that hurt him. The PlagueBringer took pity on him and bestowed to him a terrifying gift - a Great Plague like the village had never seen before.
Unfortunately embracing the PlagueBringer's Blessing eat away StarPlague's mind and he lost all his memories, his identity.
Centuries later StarPlague is still roaming around, attacking everything that moves and spreading his illnesses like a Living Curse.
Good news though : the villagers descendants know his story and are trying to right their ancestors' wrong.
They provide food and other offerings to him.
Of course that doesn't stop StarPlague from trying to attack them on sight, but they're willing to risk their own health if it means they can make his existence a bit more comfortable.
They just wish they could do more to help him, he's like a poor wounded animal and he's not even in control of his mind anymore :(
I need to create an Oc that's immune to Plague so he gets a well-deserved hug
