Xeron's mother is a succubus that is mentioned in the Armageddon's Blade campaign in Heroes of Might and Magic III: Armageddon's Blade.
According to tavern rumors, she once seduced an Erathian knight, whose soul was forever tainted by their encounter. This was when Xeron was conceived.
She was slain in battle during one of Gelu's raids. Xeron pledged revenge, and sent a note to Gelu where he promised to kill him and all he loved, as revenge for his mother's death. This confused Gelu, as he couldn't remember killing any women - except a succubus trying to drink his soul, but he couldn't really think of her as someone's mother.
