Codex city (information and stealth ops)
The Medical ward (Okay kinda obvious mad doctors/ scientists or just incredibly skilled medics)
The Foundry (Robotics and weapons development, If you're wonder this is where the experimental railgun is.)
The Compound (Basic training for soldiers. Especially in C.Q.C. combinations with a gun. It's where most of the mech pilots are also trained.)
Central Node (Links it all. Main area for custom tech and training high priority operatives. Including people with psionic powers or sorcerium users. Few of the trainees are normal humans that are extremely skilled especially the mech pilots since they have trained themselves in a scenario of losing the mech.)
My flame shines bright. Just make sure not to get burned by it.
