Mollthain, known as the god of the rampart, stands among the eight deities of the divine pantheon, embodying strength and protection. He is closely associated with supernatural forces, having served alongside other gods such as Caranthalis and Tlellic. Mollthain is intricately linked to Ygva's plans to gather god-touched artifacts and totems aimed at invoking the gods into the World Below.
The great creature set beneath Grithmaar Deep — tasked with protecting a profusion of life akin to a coral reef, left to steward a small local light source after a dominant outside light departed — was long taken for Mollthain's own essence, but is in truth his warden rather than the god himself (see Mollthain's Warden). Through it, Mollthain is bound up with the destruction of Jamal's home, which casts a long shadow over the dwarves, who now avoid the area. The offerings made to Mollthain are meager compared to those for the other gods, adding urgency to balancing the artifacts before any great summoning — establishing his role within the larger struggle over divine intervention.
Recently, the party confirmed their mission to seek the creature connected to Mollthain, having engaged in discussions with Ygva, who accepted their intention. They recognized the necessity of acquiring a Blessed Branch, a sacred item required to rekindle a pyre at Drosven’s Gate, critical to their objectives. Ygva agreed to provide a branch from the Caranthalis Altar, emphasizing the importance of replacing it should her cultivation efforts for the offered seeds fail.
The group traversed Verrow's Span, where they encountered refugees and secured the body of Askavir for examination. Sylvie's dreams and the conversations among the party reflect their ties to the Old Gods, including Mollthain. Amidst a severe blizzard, Sylvie demonstrated her magical prowess by conjuring a Wall of Flame, showcasing the harsh conditions they faced. The party's determination to return to Grithmaar Deep underscores the ongoing significance of Mollthain's legacy in their quest to recover the Living Fortress and deliver the Blessed Branch as a vital element of their journey.
In recent developments, the party's target beneath Grithmaar Deep proved to be not the god himself but Mollthain's Warden — the ancient monster he left there, radiant with Splendor. Jamal identified it as their goal, and Sylvie sent her Umbral Raven to scout, only for the Warden to destroy it. Sylvie then reached out to Ygva, who advised her on harvesting the Warden's power without destroying its essence. The party fortified their position near Grithmaar Deep, preparing for their next move against Mollthain's Warden.
