Kessel

Kessel is an evil hole of a planet, primarily notable for being host to an Imperial penal colony. This penal colony isn’t particularly interested in the reformation of offenders however, and is really more about working people to death mining glitterstim spice. Being sentenced to Kessel is pretty much a death sentence, but without the pomp and dignity of a formal execution.
