The leader of a motley bunch of Katapesh miscreats: Moukish, a talkative beggar; Khalid, a nervous pesh addict; Seef, a wiry pickpocket, and Hassfa, a brutish, grunting thug. Fadil is primarily a dealer of pesh, but he makes a decent secondary trade by peddling information and rumor. While his operation is small in scale, he has earned a reputation for discretely keeping his clients' privacy, and his followers are fiercely loyal to him.
At least, this is the what everyone believes. The unusual truth is that Fadil has no followers: each of them is, in fact, an alias for Fadil, a complex set of disguises that he maintains with quickchange, old clothes, greasepaint, and a knack for voices. He dreams of someday acquiring a hat of disguise which would allow him to add a female cohort to his group of rogues, or perhaps even something as exotic as a dwarf, elf, or gnoll. By alternating his disguises, Fadil cleverly creates the illusion of a larger organization around him, while simultaneously removing the risk of being taken out by a disgruntled follower.
