The Call of Atropus: Key of Binding

The party headed to an Order of the Gauntlet regional outpost, Southeast of Daggerford. They spoke with Eldal, head of the local chapter and the leader of the planar investigation team. They were given the key by the Order, and sent to a smaller outpost. They entered a portal to the Elemental Plane of Earth. While there, they found that they were being followed by cultists. They fought past a Nightwalker and several other strange creatures. The Nightwalker escaped through a portal. The party encountered the same helmet wearing, faceless creature as the previous adventuring group. Horace fired blasts at him, and they simply were absorbed into “his” armor. They travelled further, found a demiplane door, and fought a mountain after solving the puzzle. Each party member got dust from the mountain, and they also found the source for a weapon from the “heart of a dying star”
