Aldrassil is the giant tree and village in the center of Shadowglen, which is located in the northeastern corner of Teldrassil. The leader of Shadowglen, Tenaron Stormgrip, makes his home inside the very top of Aldrassil.
A concept art image of Aldrassil was used as the background for the priest's Holy talent tree,[citation needed] before talents were revamped in Mists of Pandaria.
According to Mark Kern, Aldrassil was added to Teldrassil during the development of World of Warcraft as a compromise with Chris Metzen, who was disappointed that the developers were unable to fully realize the entire Teldrassil zone as a 3-dimensional tree due to engine limitations.[2]
