A Daemon, also known as a "Neverborn" amongst the Forces of Chaos, is an intelligent and usually malevolent entity of the Warp that is a living embodiment of Chaos. Daemons are collectively the greatest servants of the Chaos Gods and of Chaos itself as a universal force. They are created at the whim of one of the four major Chaos Gods from a fraction of the god's own power within the Immaterium and act as an extension of his will. A daemon's appearance and intrinsic character reflect the god's own nature. These daemons may be reabsorbed into the god's own psychic signature in the Warp at his whim.
The Chaos Gods are not alone in Warpspace. They have created servants from their own essences - the creatures that mortals have named "daemons" based on their ancient legends and religious mythologies - who are not so closely bound to the Warp. Daemons are entities of a somewhat different nature to their masters, and are the most numerous of the creatures to be found in the Empyrean. A daemon is "born" when a Chaos God expends a portion of its own power to create a separate being. This psychic power binds a collection of senses, thoughts and purposes together, creating a personality and consciousness that can move within the Warp. The Chaos God can reclaim the independence it has given to its daemon children at any time, thus ensuring their loyalty. It is only though the loss of this power that a daemon can truly be destroyed, its mind dissolving into the whirls and currents of Warpspace.
As minions of the Chaos Gods, most daemons lack self-will, at least as humanity understands it. Instead, they serve only to spread the aims of their masters. For example, a daemon of Khorne seeks only battle, and wages war upon other daemons with the same fervour as it does upon mortals. Daemons seemingly spend much of their existence in conflict with other daemons, as each of the Chaos Gods seeks to expand its power and influence as part of the Great Game. It is only when the mortal world is involved that daemons tend to band together and cooperate, and even then, such alliances are short-lived, as each of the four Chaos lords seeks to prevent the other from gaining any sort of advantage.
