Back Arrow

The people of Lingalind believe the wall surrounding their world marks the edge of existence. From it fall Rakuho capsules containing armbands that let warriors transform into mechanical Briheights, so rival nations compete fiercely for every gift. Then one capsule brings not a weapon but an amnesiac man who calls himself Back Arrow. He claims he came from beyond the wall, an idea capable of overturning everything Lingalind accepts as truth. Arrow decides to reach the other side and recover his memories, but the journey makes him a target for powers that would rather preserve the world's beliefs than discover what the wall may be hiding.
