The group camp overnight in the Bastion ruins while the Brotherhood of Bones retire to the Tower of Bone. Next morning they are joined by a mysterious half-orc Monk of Irori, sent by Lastwall to investigate rumours of increased activity around Scarwall.
The group scout the area, noting vast serpentine forms in the black lake, and cross the bridge. A force of skeletons venture out from the castle, but are swiftly dispatched. Entering the gate house the party face stiff resistance from skeletal minotaurs firing giant arbalests, the battle rages for some time until Kaz's summoned ankylosaurus breaks through and the defenders are overrun.
