The Ascarna tree is prized for its hard dark wood that polishes to a sheen. However, the Ascarna tree is very dangerous, plucking up unwary travelers or flying creatures (such as birds or the pictured pesthule) with its jagged branches and draining the blood from them.
To harvest such trees stakes filled with poison are planted near the tree, but out of reach of the branches. Gradually, as the tree dies, stakes of poison are placed closer and closer until the tree is completely dead and can safely be cut and harvested.
Due to an unfortunate incident where he was called out to hunt down Lothar, who was reported to be breaking contract with both the Warriors and Thieves Guilds, Jotham lost a leg.
