One of the first things they notice when they arrive home is that Seer is acting even more unusual for herself, almost sadistic. The other detail they realize is that the cube with the 16th sigil is missing. They will have to search for it once again. Even after restoring Trista to life Seer continues to threaten and scream at anyone that will listen. Dyson agrees to watch over her to help her through this. The party returns to the labyrinth to continue the quest for the Azoth Stone. Upon arrival in the grand chamber they investigate the tower that over-looks the underground jungle, and find nothing of interest. Moving on to the only other visible structure of the space they find two bedrooms guarded by some giant scorpions with snakes for tails. At the bottom of one of the traps is the 13th sigil. Beyond the bedchambers is a prison that houses over a dozen serpent creatures. It appears they were attempting to breed them for food. Next the heroes examine steps they hug one side of the massive chamber. At the top they get ambushed through hidden arrow slits. Inside are several fire salamander and fire elementals all among the ruins of a huge ancient forge. All this reminds them of an active forge they liberated from Limbo, that was being used to construct an artifact to the Unspeakable One. The fight with the fire creatures is joined by a powerful Efreeti. After everything cools off they discover the missing cube and the not just the 16th sigil, but they also find the 18th hidden inside a secret compartment within it. All that is needed is the 19th, and they quickly locate it at the bottom of a pool. Now that they are armed with all 20 sigils they attempt to obtain the eight puzzle pieces from some animated statues they encountered earlier. Unfortunately they can only acquire seven of them, and deduce that the eighth must be obtained by an evil creature, and decide to seek K’stallo’s aid for what they hope to be the final assault. Before returning with their new ally they destroy two magical black shards that were taken off the Yuan-Ti priest. This seems to free Seer of her current episode of madness.
After escorting K’stallo through his ancestors’ labyrinth in order to acquire the 20 sigils and 8th piece, they enter the grand chamber. The only unexplored section remaining is a pit that no light can enter. In the pit is a long unopened chest with several drow crafted items and hallway leading into the side if the mountain. This hall leads them through a tomb filled with countless undead guardians. K’stallo believes this to be leading to the tomb of the traitorous high priest Im-Ravin who was responsible for the destruction of his ancient empire so many eons ago. After overcoming the traps and undead, several unknown to Theo, they reach the tomb. Here they encounter two of the most powerful advisories they have ever met, a snake like demon, and Im-Ravin himself. During the battle, Seal is decapitated by the demon and Basil is rendered so weak she can’t lift a finger. Many others are somehow paralyzed despite their defenses against such things, leaving only Tray and Theo to finish him off. After his destruction they free themselves of most of the afflictions and search for his phylactery. K’stallo is unwilling to leave until it is found and destroyed. After hours of searching it is found down a narrow crack in the wall and sitting on the ethereal plane. Several more hours of planning leads to its destruction by Trista.
After restoring Seal to life they return the next day. Armed with all 20 sigils and all 8 puzzle pieces, they open the pyramid to gaze open the massive Azoth Stone. A booming voice congratulates them all and offers godlike reward to each of them. All they have to do is step forward and touch the evil artifact. Frank makes an attempt to do so, but is stopped by most the others. During the confusion Basil slips invisibly in and lays her tiny hands on the crystal and is never heard from again.
