In Search For The Silver Dragon, Queez happened upon a group of adventurers lost in the tunnels. After finding them somewhat friendly, the two flumphs ascertained that they were looking for a Silver Dragon, which Ploom transmitted she had seen carved into a door on the far side of the Lake of Acid. They joined the adventurers on their quest, feeding on their psionic energy. She lead them to Bluecap stores, and Queez taught Tobias Villie Broadnose Cogsmith the drow's method of baking the fungi into sporebread. While harvesting this bread, the group was ambushed by Hook Horrors, and Queez was nearly killed before being healed by Ajuni Elajoral. This gave him courage to fight back, and he began helping the party in combat.
Disaster awaited, however, when the party got to the Lake of Acid. Atop the head of Marcus Cromwell like a fleshy sombrero, Ploom was spotted by a hungry and angry Cave Fisher who had just missed out on eating Ajuni. The cave fisher slashed apart Ploom with a single blow, and took her remains back to his tunnel to eat; within moments, Queez had lost his life partner. He became immediately depressed, deflating like a balloon, and Mormeros Fayan debated throwing him into the acid.
Ultimately, however, he accompanied the group to the Silver Dragon's Hideout, where a Thaluud awaited inside. He snuck around alongside the party but ultimately possessed a bit of a death wish. That wish finally came true when there was a moment where someone needed to be a distraction for the Thaluud. Queez volunteered, and Mormeros conjured an illusion of Ploom floating beside him one last time. The thaluud chased the two out of the party sightline, then brutally flattened the flumph with its massive hammer.
