The end of sand is the first area you arrive at after leaving Sea Shore in then Whsipering Islands. This area consists of a protal, a graveyard, and monsters, but no quests.
This area is essentially passible except for mobs on the sides of the trail which players can pass by. It is recommended that players proceed onto the Camp of Sacrathar where you will find a daily quest and a tribe of enemy humans.
Note: There is a sandstorm in this area which will cause graphical lag. Gameloft will most likely fix this in future updates.
There is a treasure chest around the camp area.
This is a lvl 40-41 area.
