This is the Colonizer, a human spaceship from the Last Colony. It consists of six identical compartments that are identified by colour, which are connected by four tunnels (per connection), through which four train-like carts per tunnel can travel to transport the crew between compartments. During travel it rotates along an axis in the middle, to create artificial gravity using centrifugal force. Each compartment has six floors and an air lock to allow the smaller Swarm Fighters (three from the blue compartment pictured in the front) to exit the ship without air loss. Each compartment has space and work for 45 crew members; 20 Swarm Fighter pilots, 10 cleaners and technical experts for maintenance of the ship, 5 medics, 9 cooks, and 1 compartment leader who also controls the compartment's flight (working together with the other five leaders, of course). Everyone but the pilots and the leader is also trained to man the turrets during attacks.
