Tzeentch is a god
of Chaos who represents the vitality and volatility of change. Tzeentch is
represented by a greater daemon known as the Lord of Change. Tzeentch is
closely associated with sorcery and magic, as well as dynamic mutation, and
grand, convoluted schemes. It is said that Tzeentch knows the fate of
everything, and all events transpire according to some great plan beyond
mortal reckoning. The mortal champions of Tzeentch are especially dangerous,
as they wield awesome sorcerous power on top of their considerable physical
prowess.
Tzeentch is often visualised as the serpent which writhes and twists to
represent constant change.
Tzeentchian daemons tend to be bird-like in nature, or mutated to the point
of unrecognizability. The most prolific Daemon is the Horror, an
ever-shifting mass of flesh, limbs, and flame-spewing orifices. Flamers are
slightly more powerful, with numerous gaping maws that produce the searing
flames which give these daemons their unsubtle name. Screamers are Ray-like
creatures that swoop down on foes and cut them apart with their sharp claws.
The most powerful Tzeentchian Daemon is the Lord of Change, typically an
Avian-like winged humanoid Daemon of vast intelligence and massive magical
and psychic power.
Discs of Tzeentch are melds of magic, metal, and daemon, and are often used
as transports for mortal champions. They are known as Changebringers if
they're ridden by a Flamer.
The Thousand Sons Chaos Space Marine legion serves Tzeentch exclusively. At
the start of the Horus Heresy Thousand Sons leader Magnus the Red tried to
warn the Emperor of Horus's treachery but the Emperor rejected him and sent
the Space Wolves to wipe out the Thousand Sons. Some of them escaped and
they turned to worship Tzeentch. However, following the pronunciation of the
Rubric of Ahriman, most of the Thousand Sons were reduced to dust and
trapped souls bound to their own armour. Those that survived were the
psychic Sorcerers who lead the Thousand Sons into battle.
