What if a conventional war was fought under the sea that no one has ever heard of?

And if that war were the only way for the sea to save itself from a cruel fate and suffering, the only way to overcome humans?

The sea of deaths has done so many, but man is no less.

Every day, behind an idyllic setting of landscapes, a war is fought that perhaps will never end. But is this the fate of the world? Continue to kill each other for something that you think is better than the other.
