Telmor

Telmor was a hidden draenei-populated city in Terokkar Forest. The city was located in the middle of ogre country and made invisible by a protective spell using the Ata'mal crystal shard Leafshadow. When Restalaan and his draenei party had rescued the young orcs Durotan and Orgrim who were under attack by an ogre, they were escorted to Telmor and Durotan memorized the incantation that deactivated the spell. Later, when the orcs started a war against the draenei, Durotan used this knowledge to remove the invisibility spell from Telmor, leaving the nearly undefended city open to attack. As a result, the city was taken over and completely destroyed, and Restalaan was killed.
