Phobia takes place in a post-apocalyptic world where 3 great calamites suddenly appeared on a day which came to be known as The Moment. Human architecture turned hostile and grew on its own, the border between the real and the imagined thinned, and monsterous eldritch beings known as Phobias came to feed on humanity. The story follows Noir - a soul sucking zombie-esque monster known as a Deathwalker - and his group trying to survive and find a place that'll accept them.
