Guenhwyvar

In the fictional universe of Forgotten Realms, Guenhwyvar is a magical cat from the Astral Plane. Guenhwyvar is called to the Prime Material Plane by a onyx figurine, most recently in the possession of the drow elf, Drizzt Do'Urden.

The onyx figurine was originally owned by Josidiah Starym of Myth Drannor, and has also been possessed by the drow elf Masoj, of House Hun'ett.
