Or main base is much swankier and upper class than theirs. We get to live in a large apartment on the top floor of the tallest apartment building in Violet City. Of course if any of your characters have their own places or prefer to live separate from the group, they can. Though our apartment is decked out, gaming systems, large TV's's is every room, high techs music systems, the works. Everyone provided with their own rooms to do with what they like. All paid for by the Violet City taxpayers. The one who knows their true identity and where their apartment is, is Amaryllis Lancaster. She likes to do tests on everyone and measure their powers, and makes sure they look good to the people. Though anything they need, they talk to her.
Within the apartment there is also a private elevator that goes down to a whole hidden level underground, where is a large number of training equipment. Weight and exercise machines to keep in shape, but also power specific stuff. (I'll let you guys make up what stuff is down their for your character's powers.)
