Phoenix

Phoenix city is a small military city-state fortified along the remains of the Eastern wall of what was once Kronos City. It was originally the corporation facility owned by Guardcorp, but has become a refuge and fortress after the events of the Great Exodus, when the battlebots team Phoenixbots and Guardcorp banded together to abandon Kronos and save civilians from the ensuing horde of Aether Zombies that flooded the city. Following the departure of the Hermes SFOV lander, and subsequent overload of Krono City's Quantum Fusion Reactor, the city is now an irradiated Aether beacon and overrun by Aether-starved monsters.
The only egress in and out of Phoenix is the Grand Highway, which, along with a covered roof protecting travelers from the harsh Olympus sun, also provides walls/barriers preventing the Aether Zombies surrounding the old ruins from attacking caravans
