No worries, it happens! I put a few chunks of detail for my Mordred up in his journal, but the short version is that he's been dying young/violently and reincarnating for about 1500 years now because Merlin cursed him for fucking everybody's shit up. He's very magical and very miserable. But I've also played him in traditional settings too, back when he was growing up the first time! So he's kind of a moody mess, but I don't get nearly enough chances to play with other Arthurian characters, it's a shame.
