The daemon engines of Tzeentch are awesome instruments of destruction. An unholy fusion of hell-wrought metal and daemonic power, they cast their terrifying shadows across the battlefields of the 41st millennium. In a nightmare of death they destroy untold thousands for the greater glory of their master, Tzeentch the Lord of Change.
Tzeentch is the dark Chaos god of Change. His twisted motives are often unfathomable and his weapons are many but warfare is a powerful instrument of change and the followers of Tzeentch are often at its forefront.
Sorcery also falls within the auspices of Tzeentch and many of the most potent psykers and mystics sacrifice to him. Welded together from the soul-stuff of daemons, the war engines of Tzeentch are arcane creations which fly above the battlefield on the unseen tides of the warp. Power draws power and the very presence of the daemon engines of Tzeentch strengthens the grip of Chaos on the material universe.
The Silver Towers of Tzeentch
The Silver Towers of Tzeentch form an outlandish sight on the battle field. They appear as clusters of intricately carved and fluted towers resting upon a circular island and topped with slender minarets of gold or bronze. Each tower is a subtly different creation of disturbing beauty, with snouts of weird, magically-powered weapons studding their walls. The most disturbing aspect of the Silver Towers is that they are not land-locked but drift through the skies above the battlefield. Each tower contains dozens of Tzeentchian Thrall-wizards who focus their powers to rain magical destruction on Tzeentch's foes. Most potent of all are the wardings woven about the towers, so as they advance, a wall of magical energy springs into being between each tower and its neighbour.
Doom Wing
Doom Wings are fast attack craft which streak across the skies on glittering metal wings. They are driven by three powerful engines and are armed with a deadly underslung flame-cannon for strafing ground targets and attacking airborne opponents.
Fire Lord
Fire Lord heavy assault bombers are a soul destroying sight as they rumble through the skies towards their targets. The jewel encrusted hulls of these mighty daemon engines are studded with swiveling lascannon. From their majestic wings two more flame-cannon jut forward like the pinions of some flying monster of legend, while beneath their span a deadly cargo of firestorm bombs cluster, ready to rain down a maelstrom of death on their helpless foes below.

Tzeentch Warp Palace
The dreaded Warp Palaces of Tzeentch resemble huge baroque fortresses or bastions mounted upon a colossal hovering disk. Fluctuating sparks of Warp energy flare out from the turrets and crenellations and the air crackles with the aura of magical energy. In this manner it resembles the more commomly encountered Silver Towers of Tzeentch, but does, in fact, dwarf even these feared engines of Chaos.
The Warp Palaces are constructed in a manner far beyond the comprehension of even the most learned of the Adeptus Mechanicus Tech-Priests. These floating monstrosities are known to appear above the battlefields of the 41st millennium drawing upon a raw power that is unimaginable to other machines and daemon engines.
Occasionlly the Warp Palace will sit motionless in the midst of its enemies, strafing ground targets with its various destructive forms of attack. At other times it will simply disappear with a sonic boom and a cascade of lightning bolts only to reappear again at the opposite flank of the battlefield in the blink of an eye. However, the Warp Palace is not just a nightmare union of metal and ferocious firepower. At the core of each Warp Palace lies the essence of a Changer of Ways - a Greater Daemon of Tzeentch.
