Archimonde

Luna is a first generation that was created by the Old Ones as the Godess of Luna a planet orbiting earth that the God of Luna named after her and this was a position that she held until her death during the Luna War of Conquest.

Luna would confront her beloved husband on the Exodar during his second attempt to convince their son Valen to turn to Chaos but stopping this they engaged in a fight which Luna was severely outmatched by her husband and despite Malekor attempting to spare her she would force his hand and was killed during the fight which led to a demoralized Malekor fleeing the Exodar with Kil'Jaeden and thus allowing Valen to escape Luna with the Exodar.
