Cosmos

The Cosmos is how the BioWarriors refer to the human host body. Inside the Cosmos, BioWarriors represent cells, and their body parts represent cell components, which retain the real-life functions of their biological counterparts.
The events of BioWars take place against a variety of exciting and visually-stunning locales, including the pulsing tunnels of the bloodstream, the roiling oceans of acid in the stomach, the bucolic fields of alveoli in the lungs, and the dark catacombs of the bone marrow. Other regular locations include Lymph Outpost 1818, Macrophage Base Alpha, and the Council of the Mind.
