When scientists accidentally opened a portal to a different dimension, a being came through: Janus.  Janus' coming changed the world.  People found themselves developing Classes.  Before they knew what was happening, the world was full of warriors, mages, and everything in between.  Those who didn't accept Janus as their god soon perished.  Over a decade has passed.  Basil Thorn, who was 8 years old when Janus came, finds himself graduating from college at the age of 22.  Unlike his peers in the Warrior Course, the Mage Course, or any of the other Class Courses, Basil is a part of one of the most important, but at the same time most looked down upon Classes.  Basil is a Dungeon Maker.
