The Helreign's elite: Valha, the enforcer, Hexa, the swamp witch, and Mistress Pheryll. Each of them are abnormal entities even in their own universe, but the be combined together like this is an even stranger situation. Add in costumes, as well... bizarre doesn't cut it!
Valha is dressed as an angel, Hexa is a witch and Pheryll is a devil. Naturally, their costumes all fit under the moniker of "Sexy" so-and-so. You'd be surprised how much variety there is in those options when you Google it. XD
These three are the hand-picked lieutenants of Empress Ursa - they are above and beyond the most powerful creatures found in Helzig (short of Ursa herself) and thus are placed in positions of power within the Empress's inner circle. While there is a Helreign caste that maintains the military and civilian side of things, Ursa's focus is conquest and keeps this trio close, relying on them frequently.
