Wessidion

Background
70 years ago, while attempting to sail the Nether's lava oceans, Wessidion became stranded on a small basalt isle after his improvised lavacraft failed. Attempts to bridge back to shore proved futile, and it took weeks for him to be found and rescued. By the time he was discovered, his lungs were charred and his eyes had been scorched to the point of blindness.

Rather than feeling hopeless for his own sorry state, he was filled with an unkept rage. He cursed every god that he could name for allowing this to be his fate, when he had so many years of life left ahead of him. Unbeknownst to Wessidion, many gods don't take kindly to being called out so disparagingly.

Before he knew it he could see and breathe like before, but simultaneously the pain had multiplied ten fold. In return for returning what he lost, the gods had sewn the very flame that had brought his demise into his very eyes and lungs. Ever since that day he has not physically aged, being doomed to remain in this state for much longer than its worth.
