Lore gems ("Kiira") were elven magic items that could only be worn by elves. They were semi-intelligent and acted as repositories of knowledge gathered by its wearer. This knowledge could be accessed by future wearers of the gem. Only elves of high intelligence could wear these gems. If these requirements were not met, the violator could become feebleminded . Even those who met the requirements and wore the gem of their own House did not find it easily controlled. Lore accessible via the gem was not immediately available to a wearer after surviving the transfer.
