The Stockwood Scrolls
The white dragon named Glazhael, also known as the Cloudchaser, was closely associated with Talis. Glazhael saved Talis from certain death amongst the freezing winter of the Spine of the World after she offered the creature an appropriate sacrifice – a great amount of iced meat. The dragon then took a great interest in the beautiful young girl, and the two formed a life-lasting bond.
Sometime after meeting Talis, Glazhael was formally brought into the Cult of the Dragon, along with, after Galvan the Blue travelled to meet with the pair. A deal was struck were Talis would become a Wearer of Purple within the Cult, and Glazhael would help guard Skyreach Castle, a floating giant castle the Cult planned to use to transport the wealth they would loot from across the Sword Coast.
It was in Skyreach Castle that the dragon was found. Talis, having met with Bob the Hermit, Grob Panzer, Glinda, Lucky Charmer, and Patris Daarendrian previously, had gotten the group into the castle without arousing suspicion, asking them to leave Glazhael alone. They did not. The adventurers stepped into its lair, then traded barbs with the dragon rather than playing to its pride – and the fight was soon on. After a fierce battle, the white tried to escape, but GroB held it still with his martial skill, long enough for Patris to strike the final blow. Glazhael was dead, and Lucky wasted no time in cutting out its heart for Princess Fluffypants.
