Situated outside the rim of the Andromeda Galaxy, the Crunch energy cascade exists at the border between the expanding universe and the ever-contracting Negative Zone. The massive energy output of the Crunch is harnessed by the Kyln and sent as useful power to more than two hundred planetary systems.
Situated directly on the Crunch energy cascade, the Kyln is a network of massive power-generating units that harness power from the expansion of the universe. The units draw energy from the cascade and transfer that energy to numerous civilizations.
In addition to producing energy, the Kyln is a maximum security prison facility that houses the most dangerous inmates in known space. It has a death rate close to 100% and has an inmate life expectancy of less than 3 years. Prisoners are brought to the Kyln by Omega Core, an interstellar detention organisation. Once there, they are injected with nano-sentinels that cause paralysis or death if a prisoner attempts to escape.
