Base 13

Not to be confused with Base 14

Base 13 is a massive underground facility located on the same landmass as Base 14. Base 13 was the third base constructed on Earth, with the 5 other bases being Bases 2 and 3, and Bases 5 and (obviously) 14.

Base 13 is mainly residential in nature, but it has high defenses around it's levels closest to the surface, making it nigh impenetrable.

The base is where 35% of the survivors of The Attack On The Crossroads were relocated to. These mainly consisted of wounded soldiers and persons of interest, including Jacklyn Micheal, who was needed to upgrade the air filtration unit in order to accommodate more people, and to repair the water purification system that had been malfunctioning for the around 3 weeks.

Base 13 is high maintenance compared to Bases on the surface. The only base more expensive to maintain was Base 5, which was located under the pacific ocean. Base 5 was destroyed 300 years ago when a leak suddenly turned into a massive breach in the cities hull. Luckily, the casualties were minimal due to the bases advanced warning and evacuation systems
