This reactor uses [REDACTED] technology both scavenged and reverse engineered from the [REDACTED] located in [REDACTED], at Blacksite Omega, [REDACTED]. Kickstarted by an IEC Fusion Core, the END Reactor (Entropic Negating Device) takes the background energy of the universe lost to entropy and turns it into usable energy. It is composed of the Entropy Core (Top), where an Entropic Singularity is kept, and the Enthalpy Core, where the energy collected is released as heat and used to vapourise vast amounts of water into steam to turn six massive and highly efficient turbines. Now with different FX, sound, and - most importantly - railings.

Not quite a nightclub, but not quite a vignette either.
