Based in the unique setting of London, your characters - whomever they may be - are to live here. They can have just moved in. They may be even without a home. They may have a high class flat on Belgrave Avenue. It's all up to you.
There is merely a catch or two. Any character with powers -- super saiyan strength, fireballs, magic, what have you, is merely a regular mortal. They may be some great Wimbledon player, or some poor defense attorney, but still. They are normal, lovely people. Or, not-so-normal, depending on how you look at it. :)
