Chaos Lords usually pay scant regard to the puny creatures and machines driven out of the sky to attack them, as they welcome the prospect of ripping a dragon limb from limb in mortal combat or dying in the attempt. Chaos Sorcerers, on the other hand, recognise the dire threat posed by a Flyer's attack.[1a]
Apart from casting Chaos Magic at Flyers, as he would against any other enemy, a Chaos Sorcerer can use an Icon of Power to strike enemy Flyers out of the sky.[1a]
An Icon of Power is a twisted piece of black metal, scorched and pitted as if by the heat of some great forge or furnace, mounted onto a ship's prow. Arcane symbols of all four Chaos Powers are etched into its surface, writhing around each other and intertwining as if alive. At the Icon's apex is a single, large crystal eye, whose cold gaze constantly searches the sky for enemies to destroy.[1a]
A Khorne fleet has no use for Icons of Power or any other magical trappings of Chaos Sorcerers.[1b]
