Phil Kelly continues his look at the life of Commander Farsight with his first campaign against the full might of the Imperium and shows how the T'au Empire's technological superiority fares against Imperial grit.

For Ianthe, war is all too familiar. A former soldier in the Astra Militarum, she now serves Inquisitor Covenant as an agent of the Throne. Her first mission sees her investigating a cult called the Children of Eternity. Falling foul of the local Enforcers, Ianthe soon learns that war in the shadows is seldom straightforward and that the local, angry law-keepers are the least of her troubles.

Two centuries ago, the Imperium of Man and the upstart Tau Empire fought to a standstill in the Damocles Gulf. Now, as the 41st millennium draws to a close, the tau have returned. As the world of Agrellan falls under attack, the White Scars and Raven Guard rush to its defence, but with the skilled Commander Shadowsun leading the alien forces, the Space Marines and their allies are hard pressed. Kor'sarro Khan, Huntmaster of the White Scars, swears that he will win the day in the most direct way possible – by taking Shadowsun's head.

Commander O’Shaserra, better known as Shadowsun, is an ice-cold military genius celebrated across the Chalnath Expanse. She is the master of the stealth battlesuit assault and the Kauyon metastrategy – a philosophy of war that emulates the Patient Hunter. But how to lay a trap for the Chaos-worshipping warriors of the Death Guard, whose ancient technology allows their fleet to rip holes in space? And how to deal with their daemonic patrons, who defy the laws of physics and shatter the logical methods that Shadowsun holds so dear?

After seven long years of conflict, the Horus Heresy nears its end. But now, as the Warmaster Horus marches on Terra to rip his father from the Throne, the seat of the arch-traitor’s power lies empty. Cthonia, a world once dominated by brutal murder-gangs, is occupied by the Emperor’s praetorians—the indomitable Imperial Fists. For the Sons of Horus, this outrage demands a reckoning.
