The Great Desert spreads across most of Rennor Province and completely encompasses the northern reaches of Myrtaan.
There are many oases found in the desert with the northern most of these being Ancients Oasis. The oases attract many of the desert creatures and often strange or interesting discoveries can be made at them. The creatures most commonly associated with the desert are the Camel, Amethyst Lizard and Manticore.
Many plants in the Great Desert have also been found to have interesting properties and many of them are regularly collected by the Enduring Harvesters.
