Eudaemonia

Generations have passed since humans implemented a powerful global technology: alter reality at a thought. Installed deep within the earth, and engineered to last millenia, is the ultimate forgotten artifact of ancient man.

Today, humans have descended to a technological dark age. All knowledge of the old devices is lost, save what can be scrounged by avid historians and mages, remnants of a foregone class who can freely use the system.

Luos, nephew of the blacksmith of the village of Hill Hill, has become apprentice to the wizard Samsian and his talking cat familiar Peezlebub. He learns that while most people have some minor magical ability, the deeper magic requires the facilitation of a familiar, a daemon bound to a mortal body, able to navigate the spiritual world.

But when Luos attempts the rite himself by summoning the daemon Asmod, proving to his teacher his capability in the occult, the daemon he binds besets the boy with a horrible truth. Daemons are not merely bound spirits. They are copies of the mage's own soul.

Together Luos and Asmod must overcome the changes in their lives and master the magical arts, because Hill Hill comes under threat of a dark and evil force.
