The group takes a few moments to explore this chamber. Obviously a place of worship, the heroes are wary of traps and search for clues and passageways. Avarthel, in hawk form, flies up to the alcoves and discovers that some of them have passageways leading up through the rock of the mountain and to the outside. Moric uses a more mundane approach, rope and grappling hook, to search another alcove while Bertrem and Sir Atreus discuss the dangers of the statues of Tiamat flanking the altar and Thissag stands guard, when a secret passageway opens in the north wall. Into the chamber walks several hobgoblins, apparently priests of the Red Hand and combat is on. Thissag reacts quickly using his newly acquired hammer, Drongrund, to blast the hobs with rippling earth and stone, disorienting the majority of them and knocking them back along the wall. Avarthel transforms into bear form, and joins the fight as Moric, in a bold move, leaps from the twenty foot high balcony, impaling a hobgoblin before quickly regaining his feet and throwing his spear through another. Bertrem and Sir Atreus engage the creatures and the fight looks to be a rout, but the priests have a trick up their sleeve. The humanoid clerics use the divine magic of their goddess to turn Avarthel and Moric against the party, urging them to defend the hobs and attack their friends. Avarthel, uses his great bear form to try and block Bertrem from advancing on his new “friend” and Moric looks to waylay Sir Atreus, but his mind controlled movements are clunky and Sir Atreus easily deflects the attacks. Quickly, however, the hobgoblin clerics are slain and the heroes are released from their mental torment.
Following the secret passage, the party finds themselves in an enormous natural cavern littered with stalagmites and stalactites, with several layers, leading deeper into the mountain. Making their way through the chamber, the groups hears a voice from their past, as none other than Jarett Nurth, the Asmodean priestess, call out to them from the shadows. “Ahh, Sir Atreus,” she purrs, “you have done well so far in your quest, tell me, where are Ian and Quinwynn? I should very much like to see them again.” she taunts. The heroes quickly strain their eyes, searching the darkness, but are unable locate the priestess, until Avarthel transforms into a wolf and uses his keen senses to notice her hiding behind a stalagmite and using magic to hide her form. Jarett then offers to parlay with the heroes. She tells them that they are doomed to fail their quest to stop the ritual without her help, pointing out that even the mighty Moric was unable to defeat Tiamat the last time he fought her. Jarett taunts Moric further, asking what happened to his friend and mentor, Sir Tren during that fight, reminding him that the once proud Kindred, now serves at the pleasure of Tiamat, and leads her armies into battle. Jarett tells the party that for a time, the interests of her dark lord aligned with that of the dragon queen, but no longer. She further tells the group that if they agree to retrieve an item from Azarr Kul’s treasure vault for her, she will give them an Orb of Dispelling, to use in their efforts to stop the ritual. The heroes ask what item she wants in return and she tells them that the item is called the Vallis Crystal, and is no bigger than her hand. As a token of faith, Jarett tells the party that in the upcoming chamber, are seven more hobgoblin clerics, but they are immersed in the ritual and that if they strike quickly, they will be able to slay the priests before they can react.
Deciding to test her revelation, the party moves forward and discover that she was telling the truth. The heroes savagely attack, quickly felling several of the priests, but matters are complicated when four ghostly apparitions float through the very walls and join the fray. The fight is intense, but the heroes prevail, largely due to the magical power of Bertrem’s Mace of Disruption and Sir Atreus’ enchanted sword Cyfiawnder. Jarett follows the group into the halls and again asks if they have a deal. The heroes, feeling that they have bought themselves some time, tell her that they must discuss the situation privately and decide to take a short rest. Moric beseeches Sir Atreus to let him talk to the priestess, desperate to find any information on the fate of Sir Tren. Seeing no other way, the knight of the Kindred agrees and Moric returns to the cavern to seek her out, and makes a deal with the devil.
Jarett tells Moric of another secret passage leading to Azarr Kul’s treasure room. She tells him of a dangerous trap guarding the chamber and the password to disarm it, and tells him to quickly kill the devil guarding the room. Armed with this knowledge Moric, joined by his loyal companions, search for and find the passage. Following the devilish priestesses instruction to the letter, they quickly disable the trap and engage the hideous barbed devil in combat. The devil fights fiercely, summoning two bearded devils as well, but the heroes are too powerful and too well prepared and the battle is short lived. In the chamber they find several treasure chests, each made of the bones of a different chromatic dragon. Inside they find gold, silver and gems and several magical items, but most importantly they find the Vallis Crystal.
Unable to determine what the Vallis Crystal is, Sir Atreus reluctantly agrees to let Moric take the item to Jarett, who indeed gives the warrior an orb and then departs. The heroes, battered both physically and emotionally fall back to the entrance of the Fane to rest for the night, preparing themselves for the terror the next day will bring.
