The big issues that appear in “The Lagoon” are:
1. The death as the trigger of remorse. Death is inescapable. No one in the world can avoid from the death. In this story the Diamelen’s death has trigger of Arsat’s remorse. His remorse of past event leads to the illusion of his life in the present. His regret for leaving his brother to the rajah's men haunts Arsat like the ghosts.
