Each terrain has its own fort, which grants various bonuses, including statistics and experience, both to the guild owning it and the guild members. These forts can be upgraded - each guild can chose from various special artifacts, which can enhance both defensive and offensive capabilities of the fort, including some magic effects. Depending on tactics, a guild may choose different configurations of upgrades for different forts. Lastly, a guild can also influence trade, for instance by adding new taxes within the owned terrain. This economical aspect of managing a controlled terrain is quite important, for it can directly influence the guild's wealth.
