It is said that one shape a jinni will never take is that of the wolf or dhi’b.
Many Arabian and Turkish jinn in particular fear the presence of wolves – in the case of Faerie jinn, they possess the Flaw Traditional Ward (wolves) and Infernal jinn may count as one of its Weaknesses the Abhorrent Circumstance (in the presence of a wolf). Magic jinn may have similar restrictions represented by the Baneful Circumstances (in the presence of a wolf) Flaw. Folklore mentions the si’lat, a form of female ghul particularly active during the day, that greatly fears wolves and will attempt to lure travelers by crying out in a distressed female voice that a wolf is attacking her.
Werewolves of Arabia
The qutrub is the Islamic variant of the werewolf, the name being a corruption of the Greek word lykanthropos (“wolf-man”). As true jinn cannot assume the shape of wolves, this creature usually transforms into a large dog, jackal or hyena instead. Lycanthropy, in the form of involuntary shapeshifting connected to the phases of the moon, is uncommon in Arabia and other Islamic lands but jinn or ghul capable of assuming a wolf-like form voluntarily are common. In some parts of the Mythic Middle East, the term qutrub refers generally to a male member of the Ghul tribe of the Jinn rather than a separate creature.
Desert Wolf (Dhi’b)
The desert adapted wolves of Arabia and Egypt are generally slightly smaller than the grey wolves of Mythic Europe or their Persian and Indian counterparts (Size -2, Str -3, Qik +3 and modify combat statistics accordingly), but are otherwise similar in characteristics to the wolves first presented in Realms of Power: Magic, page 144 or the Book of Mundane Beasts PDF.
