The Seventh, and forgotten god:

Xionakis. Xionakis is the mothergod of the six gods of the Realm.  She is the goddess of creation and generation.  After the birth of her last god child, Xionakis fell into a deep sleep.  Some say the sleep was caused by Despothes; some say it was due to the exertion required by her creation.  Whatever the reason, when Enid later woke her, she discovered that her children had usurped her creative powers to create and inhabit the Realm. 

Once the Realm was created, each of Xionakis’ children had vied for worshippers, creating divisions among the Realm citizens.  As each god accumulated worshippers, each god also grew in power.  Xionakis soon realized that the combined powers of her children could easily overwhelm her alone.  So Xionakis vanished from the sight of all the gods, using magics she had not taught them, and entered the Realm in the form of shadow and darkness.  To the open-hearted she spoke, in whispered tones, and soon there were those that heard her voice.

The Hearers of Xionakis’ voice were first thought of as lunatics, but as there numbers grew they began to find a place for themselves.  They banded together, and the Cult of Xionakis was formed.  As their numbers grew, the voice of Xionakis could be heard louder and more clearly.  Their purpose became that of Xionakis -- to subdue the other gods and their worshippers, circumscribing all parts into one whole -- under Xionakis.
