The Alatien's piece of the Stone Disk, kept by the Alatien Teller. Actually, it is only half of a piece: it is only complete when put together with the Maerum's stone. The shape of this half recalls an Alatien's wing.
When reassembled, the Maerum-Alatien stone looks like two hands clasping a core, symbolising how the two races are reliant upon, and completed by, each other.
Obtained from the Teller on Alais.
