Character Concepts: The Thief of Wind

I forgot exactly how and when I came up with this character concept. Maybe it was a character that I would play had I been playing in A Sundered World instead of running it, though it could also be a rad NPC to throw at my party as a part-time antagonist. Like a D&D-based Faye Valentine or Saffron. Basically it is a rogue that managed to swindle a wish from a djinni without it backfiring (or at least, not in an immediately noticeable way), or discovered some kind of item that grants a measure of elemental power, like a could be a djinni's bottle or air elemental core.

Now I could go with elemental heritage (or even windsoul genasi), but I like the idea of a rogue that managed to actually steal power, as it would ideally give a DM a very definitive adventure hook and a motivation for the character. 

Mechanically you can get away with this by going with a human rogue and multiclassing into wizard for an encounter thunderwave, re-flavoring it to be a gust of wind instead of a thunder clap. The problem is that that gives you one wind-based power, and only on a per-encounter basis at that. I think what I would prefer more is a hybrid rogue/sorcerer. The problem here is that none of the at-wills really have a wind-motif. Well...storm walk is kind of wind-ish, but I would prefer to reskin thunderwave and just make it a Charisma attack instead of Intelligence. 

After that it is a simple matter of divvying up your exploits and spells to taste, and nabbing Hybrid Talent for a sorcerer's storm soul class feature, artful dodger, or weapon talent if that is your thing. Personally I like storm soul because I imagine the part where you lose your energy resistances as wind shielding you from harm.
