Actually, I do love Myanus....it's a very lovely place. Maybe I'll give you a tour of it someday. Only some of my family lives on Uranus, but it's kind of a dirty planet...perfect for growing unusual things.

Anyway, a deathstar is a big headache to run and maintain, and they never really worked out a way to have an exhaust port without having a security issue - No matter how small and tight the hole is, someone is always able to push inside, and deliver a dangerous payload.

On a side note: I know where there's a derelict star-destroyer...but that's my home-away-from-home, so I ain't telling you where it is.
