Edenbound is a psychological horror sci-fi visual novel set on the lunar colony of EDEN over 1000 years in the future.

About 600 years have passed since humanity has reached the singularity. With exponential strides in technological development, the ills of the past gradually start to fade; medical advancement would soon follow, and the collection and distribution of resources also continues to accelerate at an alarming pace. With the imminent threat of overpopulation approaching, humanity initiates what is known as the EDEN Project. After several years of development, a lunar colony is developed, and the populace is ready to begin expanding and migrating to the utopian city of EDEN.

The citizens of EDEN continue to prosper, as everything has become idyllic and automated. Humanity has achieved perfection. Anything is possible; everybody has the freedom to do whatever they want. 500 more years have passed, but with enough time, even paradise gets boring. With stagnation on the rise, the populace grows weary. Communications with Earth slow down, and the numbers on EDEN start to steadily decrease. Where have people started to disappear to? Have the residents of EDEN been forgotten?

Wandering the streets of a massive vacated paradise, Eli Calvez lives out the rest of his days among the remaining denizens, finding solace in sleeping his days away; however, beset by a strange series of recurring dreams, Eli feels his sanity start to waver. Compelled to uncover the mysteries behind this collapsed utopia, the dwellers of EDEN find there is no rest in sleep.
