The latest Patch introduces a new 8.2.5 Wrathion questline which starts from the Earthen Guardian NPC. He can be found near the flightpath master at the Port of Zandalar (Horde), or the Tradeswind Market (Alliance). Ebonhorn’s mind is under assault by the Old god N’zoth at the Chamber of the Heart. Kalecgos has summoned you to come to the Chamber to assist Ebonhorn. You are sent into a journey to the Veiled Stair in Pandaria to search the whereabouts of Wrathion from one of his servants.
