Cxaxukluth

Cxaxukluth is an powerful Outer God, who is said to be one of the offspring of Azathoth.

History
Cxaxukluth is an offspring of Azathoth through spontaneous fission, and sometimes the Outer God is even referred as a "son". He is the parent of Hziulquoigmnzhah and Ghisguth and the grandparent the grandfather of Tsathoggua.

Cxaxukluth serves as a superior to other Outer Gods, such as Nyarlathotep and The Nameless Mist (who is the creator of Yog-Sothoth).

Cxaxukluth resides on the planet Yuggoth (possibly Pluto), where he used to live with his family, but they left due to his "cannibalistic appetites".

Connection to Nug and Yeb
The Second Epistle of Eibon unto his Disciples, or The Apocalypse of Eibon claims that Cxaxukluth is divided into a masculine and feminine aspect, which are Nug and Yeb, The Twin Blasphemies (Nug is also speculated to be the parent of Cthulhu).
