Of all the beings inhabiting the Outer Spheres, the spirits of the elementals are the most foreign to human nature. They possess a will of their own and are intelligent, though not in the way of men. For there is no way to fathom their drives and intentions.
Genies, the most powerful of the elemental spirits, prove the most difficult for men to commune with. Only the true masters of magic have perfected this art, which demands long years of study and risky experiments. Yet even the most adept at the magic arts cannot tame a genie, merely force it to perform certain acts against its own volition.
They say the mage Stammelford once commanded a d’ao to move a mountain blocking the view from his tower, but even he could never convince a genie to be a willing helpmate in his work or to give sound advice, for the reasoning of these creatures is beyond human understanding.
