Ten years ago, a single delver did the unprecendented by establishing a base deep within the Fifth Layer called the Idofront. A wanted criminal, a black market dealer, and a proponent for human experimentation, every bounty hunter who came for his head inexplicably vanished. Those who have met him suspect him to be a thing masquerading as human. Unfortunately for Riko's party, the only way through to the Sixth Layer is through the Idofront and a fateful encounter with him...

Romanceable.
