The piece of the Stone Disk kept by the Venar, which has been entrusted to their ambassador, Abnaxus. This is the final piece April finds; though she's pleased to get it, she does wonder why Abnaxus waited all this time to give it to her. The Venar Stone is shaped like a tree, symbolising the Venar's connection to them.
Given to April by Abnaxus in the City Green.
