A branch of the New Luna Government focused on reducing or eliminating all sentient environmental impact on the ecosystem of New Luna, mostly focused on two elements: SwarmCorps and BioCorps. SwarmCorps – Tasked with programming, directing and maintaining the massive cadre of nanobots which patrol the air of New Luna. Nicknamed the Swarm, the environmental nanobot-fabrication equipment to create it was a diplomatic gift from Waldheim in 3968. In practice, the Swarm neutralizes atmospheric evolution, including standard pollution and elemental imbalance, and provides a first line of defense against a chemical attack.
