Vengeance Hunt.

Inside a massive military base hidden at the very depths of an area inside the Green Mist Sea where the water pressure was very high and visibility was very low.

Wom! Wom!

Across a perimeter spanning kilometers, different sound navigation and ranging techniques {sonar} were employed through the hidden defense measures that were established across this military base.

This military base was located inside a crack along the massive rocks that lay at the bottom of the ocean. Inside one of these massive cracks was the base.

The crack already existed for a long time, but once the military base was relocated here, renovations took place as the soldiers occupying this treacherous region wiped off every natural inhabitant here and started developing it.
