Some villains have their own country, and with a desolate volcanic wasteland around their tower that the heroes must battle their way through. Others, however, have bigger plans. Entire solar system, maybe. Alternate universe, perhaps. And right in the middle is this place, a floating castle of doom overlooking -- well, pretty much nothing. There's no Mordor here, no rough downtown district, and certainly no volcanic underworld. The base floats in absolute nothingness.
