Cult of Tiamat

The Cult of Tiamat was a religious society of Dragon-worshipers who sought to summon Tiamat into the World.

History
The Cult of Tiamat was established by Kaemon Firegloom in the early 15th century. A devout admirer of Red Dragons and follower of Tiamat, Kaemon gathered a group of like-minded individuals, including Therdek Dunesweeper, Tazennin Dryaalis, Lalzuran Prideclaw, and Valxius, who venerated Blue Dragons, Green Dragons, Black Dragons, and White Dragons, respectively. In their search for Tiamat's blessing, the group discovered the legend of the Mask of the Dragon Queen, an ancient draconic artifact with the power to summon Tiamat to the material plane. With Tiamat's guidance the cult leaders soon unearthed the masks and each claimed one of them for their own, dubbing themselves Wyrmspeakers for the influence the masks gave them over a particular variety of Dragon. The ritual to summon Tiamat required, among other things, a large group of sacrificial prisoners and a treasure hoard worthy of the Dragon Queen. By 1444, the Cult had launched raids across the Uswonian countryside, to gather these necessities.

One such raid, led by Lalzuran Prideclaw and a Blue Dragon named Molzrith struck the town or Redbreak, although the raiders were driven off by Xendon, James, Grub, Ann, Grog, and Julia Stormwhisper, the Dragon having been driven off by Grub, who steered the Aurora into it, causing the airship to ignite.

The same party of raiders, who had defeated Sir Edwin Mountainbrace and his squire Sariel Stormblood, were pursued into the countryside by the group of students who had defeated them in Redbreak. The students, acting on behalf of Sariel Stormblood, snuck into the camp, freed Sir Mountainbrace, and, after a brief battle with the cultists, burned down most of the camp. As they fled, the students were attacked by Lalzuran Prideclaw, although they escaped. Two weeks after the failed raid, the Cult, who had still amassed a vast supply of tresure, began loading their spoils into Johsmohr's castle on Mount Gloomshear for transportation to the Well of Dragons. The Party of students arrived shortly before the castle was set to depart, subdued Dondrirog, a dragon who guarded the mountain, and snuck into the castle.
