The Sith wyrm was a massive creature that lived on the fourth moon of Yavin in large subterranean lairs.
History[]

A Sith wyrm
The Sith wyrm was originally an infant exogorth that attached itself to Naga Sadow's battleship[3] in 5000 BBY.[4] Failing to tame the creature and seeing no other use for it,[3] Sadow subjected it to Sith alchemy so that it would serve as a guardian for the Temple of Fire.[1]
The Massassi worshiped the beast as a god[3] until Exar Kun killed it[1] a millennium later[4] when the Massassi shaman Zythmnr tried to feed Kun to it. Unbeknown to Zythmnr, the spirit of Freedon Nadd engineered this conflict to manipulate Kun; Kun could only defeat it by using the power of a Sith amulet and committing himself more fully to the dark side of the Force.[1]
As the Sith wyrms were later hunted by the Jedi during the Great Hunt, it is evident that the creature was not the only one of his kind.[5]
