The forge world of Ryza is second only to Mars in its splendour. Famed for its innovative plasma technologies, it is a prime target for the Dark Mechanicum and their ally, the Warmaster Horus. As the forces of the traitor Fabricator-General, Kelbor-Hal, attack, Ryza's defenders prepare to sell their lives dearly for their world. Discover the dramatic events of the Defence of Ryza in this 108-page hardback supplement for Adeptus Titanicus, alongside a host of new rules to use in your games. Harness the strengths of six different Titan Legions using four new maniples, and bring the might of six Knight Households to bear against your enemies. Create your own Legions, choosing from a massive variety of rules, and declare your allegiance to the Emperor or Horus – or forge your own path as mercenary Blackshields.
