I never noticed that in 1105 Hilgya uses Turn Undead, not Rebuke Undead. Or rather, it didn't click with me what that meant vis a vis her alignment. Guess she's not truly an evil opposite so much as a Chaotic Neutral opposite.

Also, unless OotS rules are different from standard DnD (or Rich decided that it was better for her to have Turn Undead than Rebuke Undead), Loki can't be Evil.
