All the Shades, between the Dark and the Light.

A young orphaned boy named DX618, nicknamed “Dark” for his fear of darkness and cold, seeks to join the Royal Guard through the Initiate Guard Training Corps. His parents died protecting their village from an invasion of orcs, hobgoblins, warg riders and goblins, leaving him the sole survivor as a baby. He must learn, grow and survive after saving enough coins to pay his entrance fee to the Corps Academy, a six-week military-style boot camp where freshmen receive more combat training than standard classroom education.
