|“||All of your friends are dead.||„|
|~ One of the quotes the Heart of Y'Shaarj will whisper|
The Heart of Y'Shaarj was all that was left of the Old God Y'Shaarj after he was killed by the Titans and their Mogu army. It was placed in the Vault of Y'Shaarj after Y'Shaarj's death and left alone for millions of years.
It was unearthed in the Vale of Eternal Blossoms in an excavation. Garrosh Hellscream, seeing it as a potential weapon, revived it in the sacred pools and destroyed much of the Vale. It became Garrosh's most powerful weapon during the Siege of Orgrimmar, with it actually strengthening Garrosh, rather than corrupting him. During the final battle with Garrosh, the heart gave its power to Garrosh and sucked the Adventurers into a pocket dimension where they had to damage Garrosh to escape. In the dimension, the Heart would whisper to Adventurers to scare them.
Garrosh eventually absorbs all the powers of the Heart to battle the Adventurers, leaving it as a dried up husk, but is still defeated. The power then leaves Garrosh and but instead of reentering the Heart, it becomes the Fading Breath. When the Fading Breath vanishes from existence, Y'Shaarj was truly dead, ending the curse of the Sha.
