The House of the Black Prince is TWC's only Royal House, founded by a former Admin and Prince of TWC.
jimkatalanos was previously a prominent member of the House of the Black Prince, but his switch to Wilpuri in 2007 would appear to have had a considerable effect upon the growth of both houses. There are currently 31 citizen descendants of the Prince.
