You've not known a curse until the Ether itself has scorched you alive.

It's said that in the time before healing magic was tamed, that a great king pleaded with a dark mage to bring his strongest warrior back from beyond the grave. After a deal was struck, the warrior was brought back on a cursed blood moon.
When he returned, he lost consciousness, and when he awoke again he was soaked in the blood of the kingdom he long served.
He fled into the night, dreading the beast he would become once again when the blood moon would return again.

Blaidd's name is not his own. He was given it ages ago, by the commonfolk who'd seen his rare form every cursed moon. He doesn't remember the name he was given at birth. Despite his curse of immortality, he yearns for a sense of normalcy.
