Viconia, although I suspect that she died more often than not in BG1 and BG2, still had some following as the resident edgelady. Hence her resurrection in BG2 (where you had 10-20 seconds to react to keep her alive) after saving her in BG1 (dialogue to prevent her summary execution for murder by LEO).
As I vividly remember her battlecry of "Nightsinger, give me strenght!" the cracked faced angel in BG3 rubs me the wrong way.
