Artema, your character has absolutely no business casting wind walk in the first place.  It's a 7th level spell, something you definately can't cast.  Besides that, Djinni in 1st edition can't cast wind walk, although they can get you into the throne room with a wish spell, which is indeed within their abilities.  (however, it falls under the very powerful artifact dangerous drawbacks clause, in that the wish spells are likely to backfire if you use them too frequently.  One of the most common ways Djinni make wish spells backfire is by teleporting the wisher four billion years into the future, when the sun explodes.)
