Ah, Khavatari Aren... That name has been forgotten for many years now.
Not only did the Prefect Kasman learn from her, but so did the Flame Successor Akkan. But she went into seclusion a long time ago. Khavatari Hubai took her place and is teaching Kabart.
Khavatari Aren lives as a hermit near the Valley of the Lords. I don't know why she chose such a place, but you can go there and meet her for yourself. If you're lucky, she'll tell you what the culmination of Kabart is.
