''"Garro spun the length of Libertas around his gauntlets and plunged the point of the power sword into the apex of the turret where a screaming deamonic mask glared out with eyes of burning black."'' *⁸

Although never called a "Defiler", the machine's description perfectly matches that of a Defiler. It may be that the machine was a proto-type Defiler as the Word Bearers had been worshiping Chaos for longer than the other Legions, and would have more knowledge on how to construct such a machine. This would mean that the first Defilers were from the Word Bearers Legion, not the [[Black Legion]]. This would also mean that Abaddon could not have ordered the creation of Defilers, as they had already been in existence since the Horus Heresy.
