"An Age of Mist" is set in an alternate world where the sun never shines and the land is covered in mist and fog nearly all of the time. What begins as a classic tale of another world develops into something much deeper. As we follow the protagonist, the young Santori, it becomes apparent that he faces a far more menacing element to this world than simply the absence of sunlight. It recounts Santori's coming of age as he struggles to protect his family, and the battle for their survival against an unimaginable evil. It is a story of myth and legend becoming nightmare and the indomitable spirit of mankind to live and fight another day.
