Paperback, standalone story
Read moreRead less
Two of the sharpest, most dangerous minds in the Imperium finally share a room — and neither of them plays well with others. Archmagos Belisarius Cawl calls together key parties to crack open the secrets of the pylon network, only for the Pater Mutatis, Fabius Bile, to turn up uninvited. Guy Haley pits genius against genius and lets the fallout speak for itself.
