Drach'nyen is an immensely powerful Daemon, known to the history of Mankind to a variety of titles, amongst them the "Echo of the First Murder" and the "End of Empires". Of all Daemons of the Warp, Drach'nyen is the one most closely intertwined with humanity, as it was "birthed" when in ancient times, one of the original primitive humanoids committed the first murder by willingly killing his brother.
The primal cries of anguish of the slayed brother echoed through reality and unreality, with his suffering and his brother's evil taking shape in the Warp, "giving origin" to a being that took the name "Drach'nyen", which was the sound of pain and anger that the primitive man as his older brother killed him. Ever since, the Daemon has been tied to all of mankind, for every life taken by human hand, every word of hatred spoken in the ears of the dying, every thought of killing another to willingly further one's own goals has been an extension of Drach'nyen's influence.
The daemon currently resides within a Daemon Sword of the same name wielded by the Chaos Lord Abaddon the Despoiler, master of the Black Legion, former gene-son of the Primarch Horus, and most favoured servant of the Ruinous Powers.

Intelligence: Difficult to quantify. While Drach'nyen is tied to the lives of every murderer and murdered human in existence, its behavior is still mostly animalistic and mad.
Weaknesses: While Drach'nyen can assume form in the materium whenever it pleases, it is vulnerable without a host. This problem is obviously not present anywhere not fully material.
