The party journeys across the island and arrives at the main entrance of the Jade Pyramid, finding its massive steel doors ominously ajar. Inside the grand chamber, they are ambushed by a Stone Golem. Despite its formidable strength, the adventurers manage to defeat it after a fierce battle. Their victory unveils a hidden staircase leading down into a vast underground cave system.
While exploring the shadowy depths of the caves, the group discovers the Whispering Skull—a peculiar artifact with a gemstone embedded in its surface. Upon reactivating the soul trapped within, the skull introduces itself as “W.” W reveals that he has existed for countless years, previously bound to a cursed suit of armor, though he has no recollection of how he ended up in the pyramid.
Deeper into the caves, the party stumbles upon a tense confrontation: a chamber occupied by the Eternal Lord and Chey, an Artificer commanding a menacing Hellfire Engine. Without a single word exchanged, a battle erupts. After a hard-fought struggle, the adventurers emerge victorious, reclaiming the stolen tome.
Now, with the tome in their possession, the party faces a crucial decision—what should they do with this powerful artifact?
