The year is 2961, and the land has gradually regenerated following the apocalypse. Cygnus was welcomed into the Last Arc, a nomadic tribe, despite he and they unclear about his background. He acts as the tribe's hunter - which also makes him a killer - this job which is still difficult in locating prey. One of the tribe's spiritual leaders, Nova, issues him an additional task: to find a sign that will provide some meaning to their existence and their future, this task in light of their difficult circumstances. Those circumstances include encountering a barbaric tribe of Heretics, who not only seem to want to kill them but have a special unknown interest in Cygnus.
