The Borkeen Belt consisted of a collection of asteroids made of stone and iron. Legend had it that these asteroids were the debris from a planet that had been obliterated, and it was well-known for causing the destruction of any spacecraft that dared to venture within its boundaries.
The biggest space slug on record (up to 22 BBY), measuring a full 80 meters, was found residing within this belt. Rogar Farnoster, the acclaimed author who joined the University of Sanbra researchers in their study of the slug, set the location of the main villain in his popular book, "The Slug Named Grendel", within this very belt.
