Amaryllis, the final hope for a human race on the verge of extinction…
The Long Night has plunged the Earth into cold darkness.
The surface has become hostile, but a tiny part of the population has been granted asylum and possible salvation behind the walls of an underground city lit by a solar simulator and managed by an A.I. answering to the name E.O.S.
Up on the surface, far from giving up the ghost, humanity has adapted to an inhospitable world.
Deprived of the ability to speak, mankind has learned to communicate through an entity called the Spirit, and whose exact nature remains unknown.
More than a thousand years have passed since the beginning of the Long Night, and today sees the birth of a hybrid being in the laboratories of the city of Amaryllis.
