Zushakon, The Dark Silent One, appears as a swirling, black vortex, revered by the Mutsune Native Americans as a dire death god. He is also worshiped by the mysterious servitors known as the Hidden Ones. It is a descendent of Ubbo-Sathla. Logic suggests that Zushakon is the “father” of Cyäegha. The name is also given as Zul-Che-Quon (by West Coast Indian tribes) and Zushakon (in Mu and Xinian).
Zushakon is an alternative spelling of Zulchequon used by the Elder Hierophant Yogmosh-Voth in Mu and it is also used in the Book of Iod. A variation of this name, Zyshakon, was used by some of the American Indians.
The variant Zushakon was invented by Henry Kuttner in "The Bells Of Hell@; Lin Carter used the name and its variant in his fiction.
Zulchequon was created by Henry Kuttner and expanded upon by Lin Carter.
