The main power core of Gene's main base.
The Core is located in the deepest depths of Gene's mountain base. Access to it is strictly prohibited save for specialists or those of the highest rank.
While it is stated to be the main power generator for the base, this is a lie. The Prometheus Core, holds the remains of a kaiju which are used for the detection of other such beasts, but also the generation of more Red Light Radiation for the Evolroids and other experiments that rely on it.
