Dark Atlas Infernum

What would happen if a ghostly-looking humanoid figure suddenly appeared in your living room? It doesn’t speak, it doesn’t move, it doesn’t react. It just stands there and something tells you not to get too close. And if this same thing happened to your neighbors too? And what if after violent electrical storms —let’s call them “umbras”— those spectral beings —let’s call them “imprints”— materialized in your work, in parks, avenues, highways, shops, balconies and churches? Scientists are baffled and the true sorcerers of our time have had visions, nightmares, premonitory dreams where the world falls apart, tyrannies proliferate and sects, secret organizations and demonic cults seek a way to gain control of the remains of the humanity.
