As the illusion of beauty falls away, the true monstrous visage of this creature takes shape. Large devilish wings extend from her back and her hands end in sharp talons.

Truth Speaker (Su) Striga can emanate an aura of truthfulness that acts as a zone of truth as a free action. Creatures within this zone are not aware of it nor do they receive a save or spell resistance against its effects. Striga are not, themselves affected by this zone.

The Lords of Hell are gluttons for information. At the same time, the Hierarchy of Hell often makes for untrustworthy spies, as those underlings that obtain information for the Infernal Bureaucracy may simply use it for their own ends. To circumvent this situation, certain of the Lords utilize the striga (plural strigae) as an agent among mortals on the Material Plane. They are created from ritually tortured members of infernal witch covens, a process which creates an obedient outsider, both in type and category, beyond the hierarchy of devils.

Strigae serve as mission-oriented spies for various Hellish leaders, and in that capacity also belong to and lead cells of cultists, or small groups of commandos, acting as their eyes and ears. As they have extensive powers of disguise and deception, they are well suited for their purpose, and woe betide those who let slip traitorous thoughts around them, even on the smoking plains of the Nine Hells.

On Porphyra
Strigae are known to many courts of Porphyra, sometimes as emissaries of the Dukes of Hell, more often as spies to be rooted out. Rolterrans regularly employ them in their schemes, and reputedly have a process for identifying them in their various guises
