Some more detail on Stonewall. The base occupies the entire mountain, which is more or less hollow from top to bottom, plus the 20 levels underneath. the underground "forest" is really more of a park populated by short trees, and the floor it occupies is only 1 square mile. The light source that feeds it is actually sunlight, which is transferred from the top of the mountain, above the clouds, to the lowest level where the park is. Most levels of the stronghold are dedicated to the 100,000+ people who live there, but the top 10 levels are specifically for the Resistance itself. the top level, which is at the very top of the mountain and only something like 2000 square feet, is Phoebe's living quarters and offices. the level below that is twice as large, and serves as the armory for those in the Resistance who use weapons. the three floors bellow that are mostly part of the same room, which is dedicated to the Library. Every Stronghold has an extensive library, containing at least one copy of every text the former country it was located in produced before Tricore. They get as many physical copies as they can, but a lot of them were only available in digital form, so each library has a central mainframe, a backup mainframe, and it's own dedicated power source. below the library are mostly soldier barracks and training facilities.
