Not uncommon in stronger, higher ranked guilds with large memberships, a mole is a guild member with conflicting intentions. Their usual mode is to collect information about guild strategies, base locations and other strategic information and to relay this information to rival guilds and empires.

Moles are usually a high risk of infiltration after the recent assimilation of rival guilds. Assimilation builds the ranks of guild membership, but their loyalties may be in question if their membership was the result of hostile pressure.
