Percival: Got his invitation to the Grand Exhibition from his mentor Teague Canavan. Before the fair began he tried to track down the whereabouts of the halfling that wandered off with the drow.
Hjulnar: After gnolls (armed with spells) destroyed his village of Silverhold, there wasn’t much left there for Hjulnar. He was given a pony, 87 silver, and the invitation to the Grand Exhibition so he could try to make his way. This makes him the leading authority on silver dragons.
Merla Tealeaf: Came to town as a member of Finbar’s Over The Moon performing troupe. After resisting the urge to help Finbar “misplace” his copy of the invitation, Merla was asked to help deal with one of the drow ambassadors (Rhys) who had wandered away from the Imperial grounds. Her being from Runfield apparently makes her the authority of dealing with slightly inebriated drow. At the fair, Rhys snuck her into the Gand Exhibition tent early. There she encountered the captive drow, drank some tea, and was given a quest (to bring the orca’s children home) and a very large pearl. There was also a spider who may have been a hallucination.
When the Imperial retinue entered the “private party” area of the tent they were shortly joined by two large cat people who had backwards hands. The male was orange and white striped and the female was black and white striped. There was also a very large, very female gnoll in the group. She has black spots on her tawny fur and is dressed in a manner very similar to the drow captives. There is a grey silk cloth tied over her left eye.
