...universe beneath the ancient city of London. In Subterranea every legend and myth you ever heard is true.
Down in the darkness demons dwell and villains gather and plot. Ghosts and monsters roam long-forgotten passageways while visitors from other dimensions tear through rifts in time and space.
Deeper still, warps in reality have formed swamps, forests and vast primordial plains, on which dwell all manner of alien civilisations and curious creatures. It is said there is even a chasm that leads all the way to the centre of the Earth... where, as everyone knows, the dinosaurs live.
Only Britain’s strangest superheroes can prevent the untold horrors dwelling in these caverns and corridors from bubbling and boiling to the surface.
