Rise of the Horde
Velen, the draenei prophet, originally possessed the Heart of Fury. When he was captured by Durotan, the crystal was taken from him, along with the Brilliant Star. Ner'zhul's wish was to see Durotan's prisoners, for Velen was not alone when he was taken. Unfortunately for Ner'zhul, Durotan arbitrarily set the prophet free, but not before taking the two ata'mal crystals from him. The Heart was then utilized against the draenei by the Horde in their genocidal onslaught. The crystal was passed amongst the orc clans at each new moon, even coming to Durotan's hands for the orcs' attack on Telmor. It now lies within the possession of the fel orcs in Shadowmoon Valley.
