Azure Worldchiller

In the corners of Azeroth, stories are told of a dreaded dragon who swept a pall of torment over the land. In some versions of this story, his fiery presence brought cataclysmic death and destruction worldwide. In other versions, he is blue.

Source:

Doomwalker in Caverns of Time, Tanaris.

Notes:

This deep indigo variant of the Obsidian Worldbreaker mount is a drop from a special Anniversary version of the Doomwalker in Tanaris and seems to be a guaranteed drop (or close to) from your first kill on an eligible character. WoW's anniversary event occurs during November each year, but check your in-game calendar for the precise dates. The anniversary version of Doomwalker appears just outside the Caverns of Time, which can be reached via the portal area from your faction's main city. During the event, it can be looted once per character per day, for characters of level 30 and up.

This mount was introduced during WoW's 19th Anniversary in 2023.
