Osysa

Sphynx that lives in the temple to Ioun (also referred to as a Ziggurat in the past) beneath The Slayer's Take in Vasselheim, and ostensibly runs The Slayer's Take.
Described Kamaljiori as her mate. Directed Vox Machina to Kamaljiori when they asked in to The Vestiges of Divergence.
Uses (seemingly) a Heartstone along with some extra power from Ioun to gain enhanced divination abilities. This enhanced divination "comes at a cost" according to Osysa, but she claims it is worth it.
