UNKNOWN, Vol. 4

Ox and Ivan regroup with their friends, but before they can get anywhere, they're attacked by the empire assassin who sparred with them once before. This strange enemy knows far too much about the pair to just be a face in the antagonistic crowd, however. When his identity is revealed, will Ox and Ivan's resolve crumble under the weight of their shared past? And as all the parties vie for power and the Unknowns, will the world as they know it end up nothing more than collateral damage?
