Courtless changelings have no monarch and are loosely organized at best, but they still respect other changelings who help them out.
Like the Court Goodwill merits, Courtless Goodwill reflects a courtier's standing with the courtless community. It does not grant access to any unique contracts -- there are none -- but a character with high Courtless Goodwill will find plenty of friends with helpful advice and offers of service.
Since courtless are a social group instead of a mystical fraternity, courtless have no concept of a Mantle. Instead, a courtless changeling's commitment to their community is recognized through the Status (Courtless) merit.
