Screamers of Tzeentch
Screamers, often referred to as Sky-sharks, are the Daemonic Beasts of Tzeentch. They soar through the warp in groups in search for souls. They look more like flying manta rays than sharks in all honesty though.
Screamers are very agile due to their ability of flight and possess a feral but cunning intellect. Though they are able to use magic-based attacks, their greatest weapons are their so-called Warp Jaws which allow them to chew through all kinds of solid matter, even the armoured hide of a space ship. In a direct confrontation there are few that can withstand their jaws or outrun their wings. How these daemons remain aloft is something of a mystery, and they can navigate planetary atmospheres, the void of space, and the Immaterium with equal ease and speed. Some have theorized that they fly upon or swim through ambient Warp energy rather than upon actual air or water. As they fly, Screamers leave behind contrails of multi-colored sparks, and they emit the piercing, high-frequency whine that gives these creatures their name. Whatever it is, Emperor's Children Noise Marines have always dreamt of owning one as part of their cocaine fueled band of ROCK'N ROLL! But alas, the Master of Change always denies access to his magical zoo creatures, watching in delight as the Slaaneshi Space Marines throw a temper tantrum. Just as Planned!
Large packs of Screamers can often be found outside the realm of Tzeentch where they hunt after ships that traverse the Warp. Like all Daemons the only real burden they have to face with man-made vehicles are the Gellar Fields, which they systematically probe for weak spots. In the Realm of Chaos, Screamers roam the tides of magic, preying upon the shadow-souls of mortal creatures, lone Chaos Furies and other unfortunate magical ephemera. Once the Screamers catch their doomed prey it is torn to pieces in an eye blink, the gossamer shreds of its soul-stuff offered up as a gift to Tzeentch.
When manifesting in the Materium, Screamers hunt with a cunning that belies their rather base intellect. From this vantage point they search the ground below for worthy sacrifices to their master. Once they have located suitable prey, the Screamers dive down from on high, emitting unnatural arcs of warp lightning. Anything left standing after their initial slashing attack is snatched up in the Screamer’s jaws, to be either devoured on the wing or dropped from great heights to smash into the ground far below. As they possess only a modicum of intelligence, Screamers are often used as scouts and skirmishers by other, more powerful daemons or ambitious sorcerers. However, if control ever lapses, the Screamers return to their more instinctive behaviour and are likely to turn on their former master.
Screamers that are chosen to serve as mounts for a Champion of Tzeentch are bound in magnificent bands and blades and turned into a Disc of Tzeentch. These flying Daemonic Steeds are tied to the will of their masters, combining great mobility and calculated thinking.
