A sister clan is a clan that was born from another clan or has joined with
another clan. Sister clans play a big part in clantowns. The sister clan
is able to join with a "parent" clan to create a town. Two clans are
allowed to sister to the parent clan, for a total of 3 clans per town.
The costs to become a sister clan are listed in HELP CLANCOSTS
Note: If the leading clan ceases to exist or is disbanded, the sister
clan will be let out of that town without any penalty charge. This does
NOT cover clans that do not like their leading clan or if the sister clans
believe that the leading clan is too inactive.
