“Anyone approaching a town in the overworld that is under siege will see a temporary ‘siege weapon’ object (e.g. a catapult) next to the town. If you try to enter that town, you’ll instead be sent to a ‘siege encounter’ scene. (As with roving encounters, your fellow party members will see a special icon in the overworld that they can use to join you in that siege encounter scene.) The siege encounter appears according to a schedule and won’t leave until the schedule says it should (for example, it shows up at dusk and won’t leave until dawn). You’ll spawn into the siege encounter on its edge near an enemy camp. Nearby is a central battlefield, where waves of enemies and allies clash again and again while also being assaulted by periodic catapult attacks. On the opposite side of the map, is a squad of allies, pinned down by enemy forces as they defend the only exit. There are two obvious paths: The long way around includes a handful of low-threat enemy patrols, while barreling through the enemy camp and frontline will be quicker but far more dangerous. There’s a third option: Your allies need your help destroying the three catapults that keep them pinned down. Destroying the catapults and their high-threat siege engineers will draw out the greatest threat, the siege commander. If you can take out the siege commander, enemy reinforcements will stop coming and the siege will end.”
