Anyone figured out what the KI's are for that you get from clearing the WKR Eminence quests? They're temporary so you can obviously exchange them for something, somewhere (I tried the Eminence NPC's in Adoulin and towns).

Ligneous naakaul paragon is one of them, Flashfrost naakaul paragon another.

Ligneous one reads "Rumor states that this jewel can provide harvests bountiful enough to feed a city for centuries."
