On Midgard, more than a thousand years after the founding of the colony, life is steady and settled, civilization is comfortable and stable. With the assistance of the network sentient AIs, each of whom is styled after a god, goddess, or character out of Norse mythology, each serving a specific purpose, the world runs smoothly. If society isn’t the perfect dream established by the original colonists, at least it feels that way to most of Midgard’s citizens. But there are hidden cracks in the foundation of Midgard’s society, spawned by a mystery going back hundreds of years, and every AI who knows about it is held to an enforced oath of secrecy by Odin, the ultimate network administrator. The human population of Midgard lives in unknown ignorance of the mystery’s existence. Until the day Loki drops a hint to an archaeology professor struggling with an ancient poetic form.
