Lady Alexia Basileon named four regalia she wants recovered: Bone Ring of Jagri-Naz, Tablet of the Beacon, Ebon Spear of Arden, and Iron Circlet of Ghanor.
The party then returned to the ruins and pursued a diplomacy-first approach with beastman forces, leading to talks with Count Skleros.
In exchange for cooperation, Skleros requested practical support (supplies/resources) and asked the party to handle a nearby ghoul problem.
The party destroyed two barricaded ghouls (without opening the room first), then received guided passage toward the Great Cavern.
While traversing the Great Cavern approach, the party recovered notable loot (including a magic shield and other valuables), met Ptarmis, fought rock reptiles, and parleyed with goblin sub-chief Bellringer.
