Mysterious Red Crystal
The Mysterious Red Crystal is located in the Darkshore. Hostile moonkin are being drawn to it. It seems that embedded inside the crystal are a few small fragments of bone, as well as half of a jawbone of what may be a humanoid.
- Sentinel Glynda Nal'Shea suspects it came from Felwood and the model file of the crystal mentions Illidan. The Cataclysm quest "" also implies that a red crystal was the altar that the Skull of Gul'dan was kept on. The jawbone could be a part of the skull that Illidan did not take with him, especially considering the Warcraft III icon for the skull before its consuming had a jawbone.
- Alternatively, it may be a bloodstone.
