Osysa

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

Appearance
Osysa has a large, leonine body, feathered griffin-like wings, and a female humanoid face. Her hair and mane is light blond, and her glowing blue eyes have no pupils. She adorns her neck and shoulders with golden jewelry.

Personality
Osysa is honest and forthright, although her personality is overwhelmingly forceful. Although her power to scry upon nearly anywhere in the world were bestowed upon her at great personal cost, she gladly makes this sacrifice for the greater good. She appreciates jokes and wishes she heard them more often.

Background
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 their contracts, and watch over her mate, Kamaljiori. 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."

When Vox Machina proved their competence, Vanessa showed them the way below the Slayer's Take guildhall in Vasselheim. There lay a sealed chamber with a ziggurat-like platform in the center, a place devoted to the Knowing Mistress. Osysa, the keeper of this holy place, greeted Vox Machina, inducted them into the Slayer's Take, and gave them each the brand of the guild.

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 a vessel channeling Ioun's knowledge, her eyes flashing with a blue light, and informed them of the existence of the Vestiges of the Divergence, ancient and powerful artifacts from the Calamity. 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 Ioun's temple. 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 on the destruction of Draconia at the hands of the Chroma Conclave.

Quotations
Osysa: I have been keeper of this temple for hundreds of years-- Tiberius: You don't look a day over 20! Osysa: Interesting. Humor does not find its way to my chambers often enough these days. Tiberius: That's unfortunate. Osysa: I appreciate your candor, dragonborn.
