Fated Chaos: A Marvel SI-OC

Meet Locke Mastif, a man plagued by dreams and nightmares about a fictional character, Wanda Maximoff aka The Scarlet Witch.

What happens then, when he's accidentally summoned by her during a ritual gone wrong?

Not to mention, the Darkhold seems to have bonded itself to him, giving him a connection to Chthon and the Chaos Realm.

In addition, this version of Wanda turns out to be Evil, and having the Darkhold in his possession, Locke just became the perfect instrument to unleash her wrath.
