undergrounds isn't an exact fit for your preferences (slow-paced, no network), but since you mentioned an urban fantasy character I figured I'd throw it out there just in case it piques your interest! In short: urban fantasy AU, character and player-driven plot based around various supernatural factions arguing over real estate in London. We're very open to original characters and I know I personally would love to see a Jessica Jones! She would be able to keep her powers as well.
