Culuthas holds Spirit's Song, one of the shards of the ata'mal crystal - which was previously in the possession of the Prophet Velen. Upon obtaining the crystal, Culuthas believed himself above the rule of the Burning Legion and killed the demon forces in Farahlon, replacing them with his own minions - the Hounds and Eyes of Culuthas. The Consortium wishes to retrieve the crystal for its own use, and Nexus-Prince Haramad sent a group of adventurers to retrieve it. Upon bringing it to him, Haramad was so inspired by the selflessness of the adventurers that he sent them to deliver the crystal to A'dal, the naaru master of Shattrath City.
In front of Culuthas is a Legion communicator where the eredar Socrethar - who also resides in Netherstorm - is demanding the crystal from the dreadlord, angered that he destroyed Socrethar's demons.
