Volume 4 marks the pivotal transformation of Markus Antoney Marbello from immortal predator to unstoppable demonic force-no longer bound by flesh, morality, or mercy. Consumed by vengeance and guided by the forbidden secrets of the Devil's Bible, Markus enters the next stage of his evolution.

Haunted by the loss of his son and the betrayal that shattered his soul, Markus escapes to Los Angeles on Flight 666, determined to harden himself and rise. He takes refuge as the night clerk at the decaying Longfellow Hotel in Huntington Park-a rotting sanctuary of addicts, lost souls, and corrupted human vessels infested by weak demons. There, Markus begins a destructive sexual relationship with Cookie, a pregnant prostitute whose loneliness mirrors his own grief over Labrenda.

But the Longfellow is not just a shelter-it is a trap. A tenant is found brutally slaughtered, his room soaked in blood and human filth. The unmistakable stench of rotting, yellow pus reveals the truth: Rashma, Markus's mutilated demonic rival, has found him again.

Amid this chaos, Markus unlocks a terrifying ability from the Devil's Bible: Soul Feeding, a method that allows him to consume blood and souls without killing-ensuring eternal strength. To defy fate itself, he performs the forbidden ritual of Double-Demonizing, entering Cookie's womb to eternalize her unborn child's soul. But the act drains her life and corrupts her fate forever.

After a deadly chemical fire destroys part of the Longfellow, Markus is forced back to the streets-this time selling his body on Santa Monica Boulevard in a desperate bid to survive. He becomes trapped in a toxic, controlling relationship with Edward J. Ward, a wealthy alcoholic whose jealousy nearly gets Markus killed. When Markus's blood is ingested by Ed's violent lover Brandle, Markus hunts him down in Griffith Park, ripping out his heart in a brutal necrotic execution to prevent the rise of another destroyer like Rashma.

In the end, Markus sells the diamond he names RAPTURE, buries his love, severs his humanity, and leaves Los Angeles with only purpose: to return to Tennessee, fulfill the prophecy, reclaim vengeance-and rise as Saint Markus, Keeper of the Sacred Writ and ruler of a new demonic order.
