The party manages to broker a peace with a rival band of adventurers. Vic and Rabite leave them a few minutes of alone-time in the Inner Sanctum, and then the party settles in for the night. Oakley, unfortunately, can’t yet complete the ritual to cleanse the temple: he’s not only missing several components, but claims that there must be a necromancer somewhere on their floor interfering with the ritual. Vic, Rabite, and Oakley head off to the great hall in search of this taint, and indeed find not only their necromancer, but Mara’s corpse. She’s been strapped down on an operating table, and seems to be alive and well enough to convince the party not to attack Vadin, who she says raised her. From Vadin they learn that the Codex is locked in the vault, and that only a sanctified templar can retrieve it. Vic takes a moment to speak with a stone guardian and learns that the codex is spreading the crystal plague, and that Vadin posesses a card from the deck. The party decides to delve deeper, heading down through the secret passage in the Inner Sanctum towards the vault. When they enter the outer vault, they find a young red dragon giving orders to his kobold slaves. The party waits until the dragon is asleep and lures a few kobolds outside with a few words in Draconic by Mara (who seems to speak Draconic fluently now, for no apparent reason). A battle ensues, in which Mara is shockingly useful, Irontron manages to climb into the Dragon’s maw and blow him up from the inside out, and in which Vic connives to aquire no fewer than three cards from the deck off the corpse of the Dragon. Rabite prepares to flee as soon as the Dragon is dead, only to see an army bearing down on them. In one last moment of glory and vengeance, Rabite surrenders himself wholly to the Flames card, becoming the embodiment of flame and destroying the army of warforged that approaches from the surface. As the flames subside, the vault cracks open, and Oakly runs forward to grab the Codex before the invading army can.
