Aquarius IV

Aquarius IV is the fourth mission in the Aquarius series, founded in 2100. It was an underwater base located south of Cetrilles' equator. The permanent population was around 300, but the base was large enough to support up to 1000 if needed.

Purpose
Aquarius IV was a permanent base. Its primary purpose was mining. However, it also had cutting edge research facilities and laboratories full of various Cetrillean lifeforms. Other essential jobs at Aquarius IV included janitorial work, farming, cooking, engineering, and documenting the base.

Children were also present in the base. Families existed. While nurseries were never built because children were not extremely common, teachers were a necessity.

There were also highly classified sections of Aquarius IV dedicated to special resource mining and refining. However, these are not well-understood.

Fate
The Aquarius IV was a success for the first years of its existence. It was a thriving community of miners, scientists, and other various workers that made it a great success.

In 2112, soldiers swept through the base for an unknown reason. Every single inhabitant was killed in the span of 30 minutes.

In 2122, the Nimrod IX crew discovered the Aquarius IV coordinates and entered the base, expecting to find a thriving community awaiting them and prepared to assist them in their departure from Cetrilles. However, they realized very quickly that the entire base was the scene of a massacre. Horrified, but with only a tiny emergency base that was no doubt going to fail under the water pressure within a few months, they cleaned up Aquarius IV and converted it into their own personal base.
