Nisilbis is a planet in the Homeworld galaxy. It is the original homeworld of the ancestors of Kiith Siidim.
Lore[]
When the exiles interfaced with the intergalactic community, they inadvertently discovered the truth of Kiith Siidim when their sigil was recognized by the Bentusi. Evidence points to the Siidim being the descendants of a lost thirty-five-ship convoy that departed from Nisilbis nearly three thousand years before the exiles returned to Hiigara.
By the time this was discovered, however Kiith Siidim's numbers has diminished too far to stand on their own, becoming absorbed by Kiith Somtaaw after landfall.
