Prologue

Since ancient times, on January 13th of every year, a young human is the Chosen One - descending down sheer endless stairs into the cave where the demons live.
The Seven Sins.

This year, you have been chosen, and you leave behind your family and all of human kind to once more protect the world from the wrath of the evil beneath.
Noone has ever been back from the darkness, and knowledge is limited. Thus, I'm sure you will be surprised by what you find.
