Unknown Gods From Beyond

The Cult of the Unknown Gods From Beyond was an esoteric order of Sith Lords, bounty hunters, and secret agents that followed the ways of a mysterious leader named Lord Danzyron, who claimed they followed the words of invisible beings called Unknown Gods. The cult was commonly referred to as simple folklore, because their very existence bordered on the mythical.

Ancient times
"From far beyond the seas of endless voids of space and unknown places they came. The great dark gods join us and bless us with their omnipotent powers."

- Unknown scripture

The root of the Unknown Gods From Beyond may stem back to the earliest days of the galaxy's formation. Sith scholars believed that through a collision of unknown particles in the dark regions of space, shadowy beings were formed. Ancient scripture told of these outer entities and their dominion over the physical realm of space and time. Some speculate that the fabled Danzyron Nightkeeper was an Unknown God himself, but since nobody has ever spoken to or even seen him(besides those within the Cult itself), such theories are commonly thrown aside.

Resurgent Sith Empire
When the Sith Empire returned 300 years after it's defeat at the hands of the newly redeemed Darth Revan, Lord Danzyron sought to reveal himself and search out potential disciples for his new cult. In his travels, he met two powerful Sith Lords, Lady Pyrae, of Alderaan, and Darth Lynxs. The three set the wheels in motion and founded the Cult of the Unknown Gods From Beyond.
