Lzuruha takes on Mythic Socrethar the Eternal on US-Sargeras
"The greatest warriors of the draenei have their souls imbued into gleaming constructs, serving as eternal Vigilants in defense of their people. Originally a member of the Council of Exarchs before his descent into darkness, Socrethar has perverted this holiest of rituals, and used a warped fel construct to preserve his soul after his defeat in Talador."
