The Knight of Barghest

The Knight of Barghest is a fragment of Alexian, the part of himself that was awakened during his time in The Kingdom. Rather than a form or separate persona, the Knight of Barghest is its own being that shares Alexian's awareness.

History
The Knight of Barghest was born the day Alexian and Iylessa chose to serve the Dark Lady, at first simply a transformation for Alexian. After earning his freedom, the Knight of Barghest and Alexian, still one and the same at this point, departed and the knight remained as simply art of the man until, in a particularly hectic encounter, it awoke of its own volition and slew the being Alexian was facing. Had this been a one time incident, Alexian would have paid it no mind, but this began to happen more and more often until Alexian realized that at some point, the divide in his being had began fueling this aspect of himself until it became its own entity, inactive until required. Rather than attempting to purge this aspect of himself, however, Alexian instead decided to merge his consciousness with its own, allowing it to act autonomously while he he carried out his then job as well, the two merging into one when the Knight was specifically called upon. This "divided, yet whole" phase lasted for nearly a year before the Knight of Barghest and Alexian were called into another realm by coincidence, summoned to champion the cause of a then just ruler. From here on, the Knight and Alexian would fight for this sovereign, the knight acting on its own until it required Alexian, which was less often than one would think. While apart, the knight made a name for itself as the realm's hero incidentally, crushing the armies of the dark side of the realm, while when merged with Alexian, the knight was known as a saint, protecting those lacking the power to do so themselves from internal and external threats. All of this would change during the knight's final campaign however, when the trust of the knight was betrayed by the ruler it served.

Soul of the Demon God
The Knight of Barghest was once an ordinary dark knight, up until his final campaign in which he brought about the end of an entire civilization unwittingly due to an act of betrayal from the person he followed. Angered by this, the Knight of Barghest slew his sovereign and, in doing so, took in his power. Had this happened prior to the death over one billion, this would have had minimal effects, but having happened afterwards, the amount of negativity that followed him, coupled with the corrupt soul of his former sovereign, created a soul akin to that of the Demon God, a now long gone being. Before the implications of this could be seen, however, the Knight of Barghest entered an inactive state.

Soul Eater
Upon slaying an opponent, the Knight of Barghest consumes part of their being, granting him some of their power or an ability. Visible as black and red mist flowing from the bodies of the fallen, people likened the dark knight to a being that fed on the souls of the dead.

Demon God's Banquet

Having been infused with a great deal of negativity and part of the soul of the knight's former sovereign, the cape gained the ability to act one its own, transforming into various weapons, natural and crafted. Now directly bound to the knight, the cape takes on the form that best suits his situation.
