In Act IV of the module Faction War, the Indeps and the Xaositects gather to attack the Civic Festhall, while the Harmonium, the Sensates and their allies try to prevent them from reaching the Civic Festhall by confronting them in the Lower Ward (this is also where the fiendish incursion starts).
What i don't understand, is why all this happens in the Lower Ward.
The Festhall and the Clerk's Ward are situated between the Market Ward (+ Guild Hall Ward) and the Hive. Why would the forces of the Indeps and the Xaositects have to pass the Lower Ward to reach the Festhall?
The only logical reason I could imagine, is that the attack on the Festhall is a decoy and that their real target is to attack the Barracks.
