Oblis was a planet located in the Cularin System. The planet was destroyed by a powerful sith artifact called the "Darkstaff". Its remains have formed the Cularin Asteroid Belt. Some people believe that the Cularin System is the original homeworld of the Exogorth (a.k.a. Space Slug) species, which is said to be descendant from some sort of organism that inhabited Oblis and managed to survive the destruction of its home planet, evolving and adapting to live in the vacuum of the asteroid belt, feeding on mineral matter from the asteroids. Virtually nothing is known about planet Oblis, except that it had large crystal deposits, which gives a bit of support to the idea of a silicon-based lifeform, like Exogorths and their ancestors, evolving there.
