Djinn

Djinn are maical beings that reside primarily in the Sultanates of Rashpuht. They have the ability to fly, grow, shapeshift, and are very powerful beings; however, the djinn seem to be bound to a code, such as when invoked they must answer the questions when asked, as seen with Abdullah and Hasruel. Although djinn posses great power, they are still mortal and can be killed if their "life" is stolen from them and destroyed. The primary example of this is with Hasruel when his brother Dalzel steal's his "life," forcing his brother to do his bidding out of fear of death, driving the plot of Castle in the Air.
