• A Home Base is the only space on the board where a Hero and a Villain can co-exist without attacking each other. No duelling is permitted.
• When you land on a Home Base, draw an Event Card
• When you land on a Home Base, raise the Special stat associated with that Home Base by 1 point.

I'll put a number of different style Home Bases here with the rules written on them and a Special I think is appropriate, so players don't need to come up with their own if they don't want to.
