About Lagoon

In the far off world of Lakeland, all was peaceful. This was until an evil being known as Zerah came and polluted all of the water, making people very sick. You play as Nasir, 'The Champion of Light', and are sent into the world to destroy the demons that seem to be linked to the muddy waters. On your quest of good you'll come across people in need and help them. You're able to attack, jump, and cast magic in your adventure. You'll eventually face off with Zerah in the end.

Lagoon on Wikipedia

A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as a reef, a barrier island or islands, a barrier peninsula, or an isthmus. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.
