Legion City was the only city on Legion.
It was contained in an energy sphere which turned itself off when a ship came near. The White Rabbit was located here. (AUDIO: Paradise Frost) The city had a spaceport, and several other bars located on Main Street. (PROSE: Big Bang Generation)
The inhabitants of the city would only leave the city if they could establish safe passage. The city was once under threat from the Vesuvius when it was falling towards the planet with a core breach. (AUDIO: Vesuvius Falling)
