Tracked since by ColourTheory
The mighty Fort Hydrus was once known as Fort Paternoster. It was very advanced, and was eventually abandoned for many different bases. The base has now been converted into a water treatment plant, and is still heavily raided as it contains a good location to mine for rare minerals.
