Changes

Hayden also displays a great deal of unjustified knowledge about the [[Night Sentinel]]s, the [[Maykr]]s, and [[Urdak]], the latter being a heavenly dimension that Hayden himself stated no mortal or demon had ever set foot within (and thus he could not possibly have known about it by any normal means, let alone exhibit the familiarity with the realm that he displays). Furthermore, in the [[ARC Complex]], one of the scientists states that Hayden's cortex is alien in design, a bizarre finding considering Hayden is supposedly of human origin. His mind is then uploaded into the Fortress of Doom's systems, which VEGA describes as "similar to his own"; as the Fortress was designed by the Maykrs and the Argenta, there is no explanation for how Hayden's supposedly human-made body could interface with it so easily. While it has not been confirmed that Hayden is in fact the Seraphim, it seems that there is more to this cyborg than meets the eye, especially in light of the discovery that VEGA and the [[Father]] are the same being.
