Djinn

I don't believe that Tom is a djinn.

What's the difference between a djinn and a genie?

What's the difference between djinn and demons?

Are there benevolent djinn?

Necromancy meant originally the conjuring up the souls of the dead, and later included the conjuring of all sorts of inhuman spirits such as sylphs, giants, and djinn.

I would have liked to know whether he thought this was due to the climate, the diet, or simply malefic djinns.
