If Legacy of Fire were to get an anniversary edition, one of the things I hope the people at Pathfinder do is to incorporate geniekin into the region. Haleen is an excellent way to start. Her stats fit nicely into a Dervish of Dawn style and her personality fit that of a typical Ifrit.
Her stats on her own would give her 18 Dex, but a pitiful 6 WIS. I switched the points distribution from CHA to WIS to compensate, giving her the same stats as her updated form. CR wise, there's only one issue with her. As an ifrit, she won't get an extra feat at 1st level. Bumping her up to 5th level to match Pathfinder standards cover her feats, but she would still need Dervish Dance to use a scimitar. With that, I got rid of Weapon Specialization to compensate.
Lastly, I gave her Desert Mirage as she won't put Fire Affinity to use as a fighter.
