Extended universe sigil Yomagn'tho (That Which Restlessly waits Outside) is an Outer God. It appears as a flaming circle with three inner-petals, and a dark interior, in which chaotic shapes are discernable. It comes from a world circling the star Pherkard. It is said to be equal in power to Cthugha. Some texts call it "the Feaster from the Stars" although that title is more commonly associated with Zvilpogghua.
