The Lost Desert is north of the San Blanc Shore and southeast of the Portal to the World. This desert conceals the Portal to the World and dominates the northern tip of the Western Continent, along with the range on mountains connect to the Iiyella Volcano.
The battle map for this area consists of a desert area with two large cliffs and a lower are in-between. The Deployment Area is on the smaller of the two bluffs on the lower-right side of the map, a larger bluff can be found on the upper-left side of the map where the majority of the monsters deploy initially. In between the two bluffs and a little to the side is a lower area where a few more monsters tend to spawn. The monsters usually found on this map include: Griffins, Basilisks, Salamands and Sand Glms.
