• In early PTR builds, his Adventure Guide entry read: Xy'mox and his most loyal associates caught wind of the Forerunner's Relic, an ancient Progenitor artifact said to unlock the key to weaponizing Ephemera. To defeat Azeroth's heroes this time, Xy'mox must unlock the power of the Forerunner's Relic during the encounter to turn this deal in his favor.
• In a later build, it was changed to: Driven by greed, Xy'mox lead his most loyal associates to the Sepulcher of the First Ones. Using the chaos to plunder its riches, Xymox [sic] seeks to weaponize ephemera in order propel himself to unlimited power.
