The party slept in the relative safety of the artifact chamber and then decided to head back to the surface to hunt down Karus' Ent. The party decided that the route back to the surface should be the one they'd entered through, choosing to ignore the arboleth hole.
At the entrance, the No Pants Brigade found that a weathered but solid wall had been erected across the open wall of the building. As they approached it to determine a method of egress, it fell on them, revealing it was actually a transformed rock golem.
The party was hurt a bit by the surprise attack, but quickly rallied. Vallo called his punishing eye and Adah-Kah shoved the golem through his lesser golem sidekicks, knocking them all over. Meggido and Adah-Kah closed in on the big golem as the rest of the team decimated the minons.
The golem fell quickly, though not without having taken some serious damage as the golem collapsed on them again. They took a break to tend their wounds and Vallo summoned a wilderness guide and asked it to lead us to the Ent's grove. The party mounted their summoned boars and set out. On the ride, though, both Vallo and Adah-kah were visited by the Watcher. When they awoke, they shared a bit of what they'd seen and the party returned to hunting Karus' Ent.
The group was led to the grove and found the Ent, who didn't respond initially. it looked old and nearly dead, but was clearly still a threat. The party prepared itself and the fight was on. Vallo gavr Adah-kah an enchantment to set his sword aflame, which Adah-kah was happy to accept.
Everyone sprang into action, scoring quick hits on the Ent. For his part, Adah-kah stabbed the tree with fire in the face. TWICE.
The Ent tried to strike back, attacking everyone at once but it only managed to hit Sardis and Vallo. It followed that up by starting to grab partymembers, especially Meggido and Adah-kah. Unfortunately for the Ent, the party was happy to stay close and use the firey weapons they carried to set the Ent alight and finish it off. As it burned, it revealed a semi-fetal Dryad-lich, Karus, who also died in the fire.
Taking a moment to assess the situation, the party discovered that Sabriel's sense pointed us at the desert. They discussed going over the mountains or through the abandoned dwarven tunnels.
