Prism Academy: Inferna

Humanity stands at the brink of extinction.
Earth has been bombarded by forces beyond our understanding.
In the aftermath, monsters rule the Earth while humanity
is forced into a few small safe zones, but not all is lost.
When the shadows fell, so too did hope. Progenitor rays
birthed a new breed of humans, known as supers.
Now those few are all that stands between mankind and
death upon the claws and fangs of monsters.
