ToME: the Tales of Maj'Eyal

In the sacrifice dungeon, most enemies are from Fearscape faction, but some chest guardians spawned as Rhaloren (sic?) and thus friendly, at least to a skeleton with the cloak of deception.
They spawned like normal enemies - with rare dudes, auras, arcane disrupted auras and whatnot, just not hostile. Didn't get any of them to contact their less friendly brethren, though.
