The world of Twilight turns in the darkness, illuminated by the ethereal glow of the god-planet, Kerberos. This is a world of heroes and monsters, in which four unique individuals will stand against the end of everything. One of these is Kali Hooper, archaeologist and adventurer, exploring the lost places of the world and uncovering the mysteries and artefacts left behind by lost people in ancient days. Battling the forces of the sinister, oppressive Final Faith – stopping only occasionally for a pint at the Here There Be Flagons – Kali will unearth the secrets of Twilight's past and discover the fates of the vanished Old Races. And, perhaps, she will reveal the truth of her own beginnings...

This omnibus collects the books The Clockwork King of Orl, The Crucible of the Dragon God, Engines of the Apocalypse and The Trials of Trass Kathra.
