A magical storm conjured by the Samurai, a group of mages with designs of their own on the treasure, pushes them off course. What could have scuttled the entire mission turns fortuitous when they discover the mystical treasure of Neptune's Cat. And once Orains puts on one of the collars, things may never be the same again. This is a standalone short story set in the Musimagium universe.
