Desert King

Its roaring is piercing marrow and bone and can be heard over ten miles away. The Desert King is the undisputed ruler of its territory and no one messes with this animal. Show no fear and prove yourself worthy of its trust and you will get yourself a valuable companion for your adventures.

It can be bought since Update 10.51.
A sprite for the creature version of this mount was wrongly displayed on the official Library entries for Noble Lions and Roaring Lions since their implementation until September 2020. Unlike the creature versions of Armoured War Horse and Shadow Draptor, this sprite has never been implemented into the game client.
