During the night Valthrun and the villagers had been busy moving rocks and preparing the temple for its new expansion that was intended to secure the crystal skull. Valthrun including a number of counter measures to protect vs theft or magic. There was also the suggestion that Barwain might have more potions but the lord was out of potions having given the party his entire supply. Lastly before leaving Valthrun, visibly exhausted, related two verses from his research that lead to hope for the group. First was even if the cultists are lead by a much more powerful caster the caster is unable to do much else while conducting the ritual without disrupting the ritual itself. Second was a tale from a book of erotica that covered the tale of a disgraced knight leaving the order that guarded the keep. It described multiple levels beneath the keep and mentioned a shrine of Bahamut beneath the keep and if that shrine still exists it may be a place of succor.
The party set out for Shadowfell and found the fortress ruined but with signs that the area had been cleared and an entrance escalated fairly recently with significant travel in and out of the steps leading to the depths. and entered the land below Shadowkeep. There was a pit and a group of goblin guards. A swarm of rats from the pit gave the group some trouble. The guards were defeated and while several party members were moderately worn out from their efforts.
