The Unveiling

He embarks on a journey to find out who he is, and his purpose. Along the way, he discovers that his arrival heralds great changes to humanity as a whole.

The story is set in a post-apocalyptic era where whatever damage has happened. People see the prosperity of the ancient humans, but have no idea what led to their death.
