Unidentified Sith Empire conflict

"During the same war that birthed the silooth, the Sith introduced the warbird and the war behemoth."

- Sorzus Syn

At some point prior to the arrival of Dark Jedi Exiles on the Sith homeworld Korriban in around 6900 BBY, the Sith Empire became embroiled in a conflict. During the war, the Sith pressed into military service for the first time various varieties of warbeast, including the silooth, the Sith warbird and the Sith war behemoth, in order to aid their campaign. During one major engagement of the war, the Battle of Kalsunor, hordes of mutated silooths were released by the Sith on the planet Kalsunor, and the creatures proceeded to ravish the world.
