The landmark after you've reached the ocean seed and brought back life to the area
The landmark before you've cleansed the sand away
Sword of the Sea - Cleansed Landmark
This was a concept to show the difference in what an area might look like before and after you return life to it. The sandfalls that once blocked off your path would turn into waterfalls, the huge piles of sand would turn into vegetation, and animals would return to the area.
