Droki
A Derro with a hat that has two tentacles of a displacer beast attached. Gets around Gracklestugh, is not very willing to talk, but eventually allows Kais to trail him.
Plays the middle supplying magical items to whomever will pay. He reportedly once said that he stays indebted enough to prevent his own death, but never too indebted so someone powerful wants him dead.
After disrupting a ritual, adventurers found Droki's note to Nerrick which revealed Droki's connection to the curses which befell Clan Cairngorm, and later showed the note to Hgraam.
