Exploring the ruins of a collapsed section of the palace in Morenor, the party encountered a hive of Carrion Crawlers and their hatchlings, a veritable swarm of poisonous worms of all shapes and sizes. Harkin managed to miss most of them, aggravating them to the point where Gamlock came to his rescue the dwarf ended up taking most of the hurt. In the end, the party smashed, sliced, or (the most effective option) incineration blasted the crawlers to pieces.
In the aftermath, Gamlock and his dwarven stonesense felt a small breeze in one of the antechambers of the collapsed wing of the palace, leading to a secret passage. After exploring it, avoiding a few traps and discovering more hidden ways, the party found its way into the palace. The rooms they explored have been thus far clean but empty, and Esry discovered the entire place was suffused with magic, seemingly bound to the gold that made up its construction.
