Throughout the game, you will encounter large, ominous pyramid-like structures that emit a red, disruptive energy. These structures represent the primary 'antagonistic' force in the narrative, causing harm to the ocean's ecosystem.
However, you do not 'fight' these structures. Instead, your goal is to understand their purpose and ultimately neutralize their negative influence through activating ancient technology and restoring balance. This is a narrative challenge, not a combat one.
