Duchess Nina Heeate L'andariel is an archdemoness, the Lady of the Duchy of Southern Yamato and the leader of the Southern Horde in the Third Age. She's the younger sister of Duchess Vaetris L'andariel of the Eastern Horde. She infiltrated the Southern Horde by posing as Duke Hepnaz L'invrad's Dreadlady Gin'vel. She eventually betrayed Hepnaz and usurped power within the horde and also forced Duke Malphas d'Xuvadon of the Northern Horde to become her pawn by putting him under a geas. Nina intends to unite the four demon hordes in order to pave way for her sister Vaetris's return.
