Forum:KB:Star Wars Space Hulk

I'm putting together ideas for a Star Wars fan game, and I am searching for a concept that I imagine probably exists in the Star Wars universe, but which I can't seem to find via normal searching methods. Essentially, I've been inspired by the "Space Hulk" from the Warhammer 40k universe; it's basically a mass of wrecked ships and other debris that has been clumped together by gravity over time, and is filled to the brim with both useful salvage and dangerous creatures.

The Star Wars canon and Legends are lousy with big space battles, so I'm sure it's possible for something similar to exist - assuming it already does, and has a name, if anyone could link me to some information that would be amazing. Failing that, if this concept somehow hasn't been used in any Star Wars media yet, can anyone think of a major battle that occurred in deep space (i.e. not in orbit of a planet) that I could reference as an origin point for the space hulk's formation?
