Captain Orion Grant has just received the job of a lifetime-smuggle an ancient artifact to the other side of the world and sell it to an airship corporation for an enormous payout. That is, of course, if he can avoid the relentless mercenaries that are after him, or outwit the traitor aboard his ship. Meanwhile, the Assembled Court is searching for this same artifact-an auger's marble that holds the key to manipulating the deathly fog that enshrouds the ground world. William Lamont is a Cleric for the Assembled Court who has been tasked with tracking down Orion Grant and his crew. Disillusioned with the religious government he serves, Lamont is faced with deciding between protecting his superiors and finding his own personal salvation.
