Xel'na

A formerly-human mage, turned lich and demon-follower of the Twisted (becoming externally mkhulu, despite being undead). In life she was a lover and worshiper of the White Skull; after her death and rebirth into lich-hood she became extremely jealous and possessive, so they broke up. She went full stalker and turned to the Twisted in an effort to gain the power to win him back. Eventually, she allied with Gozh in his plan to supplant the Watcher. These efforts were foiled by Enigma, who defeated her three times (the third, in the core of the great volcano under the Dragon Congress) led to her final death when Gozh betrayed her phylactery into Enigma's hands, who then turned it over to the White Skull. It was yeeted into the Oblivion Gate in an experiment.
