There Is No Light: Enhanced Edition

After a massive catastrophe, the remnants of humanity took refuge underground, where they founded a new religious society. Having forgotten the sunlight, they blindly worship the god of the new world – the great Hand, which once every few years descends to the Central Station to people and takes the chosen newborns to itself, to a world hidden behind the huge gates of the Temple. The protagonist sets off on a dangerous journey through a hostile world, hoping to find a way to open the gates of the Temple and return his child.
