Three Barbarians

Three Dwarves, those descendants of Orzeca, otherwise known as barbarians by all the Ahib, are the ones who retain knowledge of the three materials needed to craft the Gem of Imbalance Knowledge Item - the first being Olun's Heart NPC Knowledge Item, the second, the Cup of Oblivion Knowledge Item, and the third, Tunta's Seed Knowledge Item.

Burt Bedmountain NPC Knowledge, the first barbarian who guarded the Crypt of Resting Thoughts, knows of Olun's Heart NPC Knowledge Item. Lafi Bedmountain NPC Knowledge, the strange graverobber who spread the precious knowledge of the Crypt of Resting Thoughts to the world, knows of the Cup of Oblivion Knowledge Item. And finally, Orkalis NPC Knowledge, the acknowledged barbarian, knows of Tunta's Seed Knowledge Item.
