The new Guild Strongholds will enable guilds to employ additional lines of defense to protect the Emperium, and thus ownership of their Strongholds, from rival guilds. The introduction of Fortress Gates and Gate Houses in the new maps in the War of Emperium SE Update and the overall reduction of Warp Portals within these Guild Strongholds will require new and more daring strategies for conquering guilds to shatter Emperiums and take over Strongholds.

Gate Houses are occupational points that must be conquered to open the Fortress Gate that leads to Emperium Room. Each Gate House has a Guardian Stone which enables the Stronghold`s owner to summon Guardians if he has attained the Guardian Research skill. The gate to the Emperium Room will open if all Gate Houses are occupied and the Guardian Stones are destroyed by the intruding guilds. If the Gate Houses are reclaimed by the castle owner, then the gate will close again. Any intruders that have passed through the gate into the Emperium Room will be trapped inside: their only viable choice would be to desperately try to destroy the Emperium before the Stronghold`s owners can stop them.
