Sphinx

Sphinxes are a race of intelligent, immortal magical beasts. A sphinx guards in sacred isolation the secrets and treasures of the gods. Its great wings sweep along its flanks, its tawny leonine body rippling with muscle and possessed of forepaws powerful enough to tear a humanoid in half.

Androsphinx
An androsphinx bears the head of a humanoid male on its lion's body. Outwardly gruff and downcast, it often begins conversations with insults or negative observations. Beneath this gruff exterior, however, an androsphinx has a noble heart. It has no wish to lie or deceive, but it doesn't give away information readily, choosing its words as wisely as it guards its secrets.

Gynosphinx
A gynosphinx bears the head of a humanoid female. Many have the regal countenances of worldly queens, but some are marked with wild, leonine features. A gynosphinx's eyes see beyond the present time and place, and penetrate veils of invisibility and magic. Supplicants who look deep into those eyes might find themselves magically displaced, banished to some farflung plane where a difficult trial awaits them.
