Osysa is a gynosphinx residing beneath the Slayer's Take guildhall in Vasselheim. As an NPC, she is played by Matthew Mercer.



Osysa has a large, lion-like body, feathered wings, and the face of a female humanoid with a mane of ashy blond hair and glowing sky blue eyes with no pupils. She wears jewelry wrapped around her neck and shoulders.[2]




Osysa has been the keeper of the temple to Ioun within the cavern beneath the guildhall for hundreds of years, scrying via a heart glass in the altar with which Ioun extends her vision to "watch the world." This allows her to locate the guild's quarry, determine the viability of contracts, and watch over her mate, Kamaljiori.[3] Her clairvoyance pierces through planes, becoming easier to block the farther it extends. While apparently possible, she states that a prior attempt to peer into the Abyss was a "dire mistake."[4]

Vanessa again brought Vox Machina, along with Kashaw Vesh and Zahra Hydris, before Osysa when they returned to the Slayer's Take to ask for aid against the Chroma Conclave. She became possessed, a blue light overtaking her, and informed them of the existence of the Vestiges of the Divergence, "relics wielded when the gods walked and fought alongside their creations."[5] She offered that her mate, who resided "south of the Frostweald," would be able to aid them further in seeking the Vestiges, but indicated that it was in her nature to challenge them by not giving any further information on his whereabouts.

Osysa reprimanded Vex'ahlia for mentioning Vecna within her temple to Ioun. After Vex and Percival explained what they knew of Vecna, Osysa scried upon Whitestone and noted that the ziggurats were not of Vecna's construction, but rather that he stole them.

Osysa also scried the destruction of Draconia at the hands of the Chroma Conclave.[6]
