The Mysterious H

The Mysterious H is an unnamed civil servant and suspected trained Hassari in league or controlling of Wassim al-Kapur. There is some suspicion he has some connection with Riad ibn-Dajjium, the Hassari student killed by Raof al-Kapur (a distant cousin of the ruling al-Kapur's of Darvish Kapur). 

He first became known to the party when he hired a skilled pickpocket to steal the Magical Brass Oil Lamp from Raouf and sent him on a wild goose chase to what could have been his doom on the Isle of the Fey. However, Raouf and his friends managed to survive the trials only to return to Darvish Kapur to hear H had already assassinated the Sheikh. 

He is believed to orchestrated the purging of much of Darvish Kapur's Majlis and hunted down Raouf and Maissa's adventuring party, ultimately resulting in the destruction of the Mosque.
