Witcher universe campaign. So if anything is wrong blame the GM because I don't really know anything about The Witcher.
Character is a secondborn twin Noble, was destined to be the double agent of the firstborn son, for that purpose was even given the same name. Thirdborn was a font and sent to a mage school early, and fourthborn a good for nothing.
It's a bit of a long story about how him not being able to handle the dirty work he was supposed to do as the "double", aswell as his rancor and jealousy of his other brothers ended up being the house's downfall. With the main thing about it being that he freed a criminal mage which did it all. The first time he did it was kindness, the second time it was rancor/jealousy/rage.
After that, he realized he had no real name, but taking other people's names was also his only talent, so he took on countless names while traveling, ended up setting with a joke name he made for a fool at some tavern, mainly because it represents the opposite of his personality, Adamantine. But it's also the persona he likes the most, a Neutral Good traveler.
He then went to the mage academy, in witcher the DM told me there was two, one all-women and the "better" one, and a all-men one, where the thirdborn probably is. He didn't care about family anymore, he was already free, but didn't want to be "The Second" again, so he took an act that could be called insane and mutiled his own genitalia, said it got mutilated while he was young and because of that they never knew his sex properly.
So he ended up in the all-women academy as a man(?) mage. In there he stopped taking other names, and was just himself, which ended as him being called extremely nasty in the rumours and being know for as "Black Liliana", mainly because he is inexpressive and the only emotions he shows is jealousy or annoyance. Black Liliana is neutral evil.
He still sometimes runs off to travel though, he loves being Adamantine the most, even if that is just a "fake name".
