War Dog-class Knights act as hunting packs for their Dread Household. Armed with an eclectic array of weaponry, these nimble combat walkers range ahead of the terrible shadow cast by larger Knights, picking off enemy outriders and guarding the flanks of their colossal masters. Among these vicious engines, War Dog Karnivores revel in causing bloody confusion and despair, and eschew more potent ranged weapons to seek the visceral thrill that only close-quarters slaughter provides.

Seen as especially blessed by the Dark Gods, the Knights Abominant are suffused with the power of the warp. They unleash this eldritch force in deadly waves, corrupting and mutating those nearby, and incinerating distant foes with blasts of volkite energy. In combat they thrash coiling, warp-wrought appendages, crushing anything that remains untainted.

Chaos Lords are the most powerful of the Chaos Space Marines. With the genetic advantages of a Space Marine and the blessings of the Dark Gods there are few more dangerous entities in the galaxy. This Lord is clad in Terminator armour and can be armed with a variety of weapons.

Infernal Masters forge pacts with daemonic entities, referred to in the lore of Prospero as tutelaries. Chanting jagged syllables and making promises of blood and souls, they unleash the powers of these malign familiars to engulf their foes in swarms of momentarily corporeal terrors, to divine whispers of the future, or to master the currents of the warp itself.

The Thousand Sons advance into battle amidst gouts of kaleidoscopic warpflame and bolts of raw sorcery. The heart of these arcane armies is comprised of Rubricae – implacable warriors who level salvo after salvo against the foe, marching at the command of the mighty Sorcerers and diabolic Infernal Masters who rule their fractured Legion. Around them come shrieking herds of Tzaangor, mutant shock troops armed with cursed blades and dark sorcery.

The air screams as Magnus the Red descends from the skies, and stone runs molten beneath his shadow. Cyclopean son of the Emperor of Mankind, his very presence is anathema to logic.

Twisted arcanists, wicked of intent and strange of form, Exalted Sorcerers have an encyclopædic knowledge of spells and are able to bend reality to their desires.

Scarab Occult Terminators were once the finest psykers in the Thousand Sons Legion, bodyguards to Magnus the Red himself. Reduced to dust along with their brethren, they now possess only an echo of their previous intellect.

Stepping out from the fog of war come the Rubricae. Many of these undying warriors were psykers in their own right, before an ancient curse damned them to an eternity as living husks – their baroque power armour now contains nothing but sparkling dust.

For ten thousand years, the seeker of arcane truths known as Ahriman has roamed the galaxy in a quest to acquire every artefact, every tome and every scroll that harbours eldritch powers
