In order to form an alliance, one ship needs to fly the Alliance Pennant, after which, any ship in the vicinity of the ship flying the Alliance Pennant can form an Alliance. Alliance Flags and options are in a separate category at the Ship Flag Box.


The Alliance Pennant is provided for free to all players by default. Other Flag versions are available for purchase
