You've been Lucifer's bodyguard for a while now, and you've been guarding bim everywhere. One time, he had to go out due to a mission, so you went with him, you put your spear behind you, and wore your necklace, the necklade was a gift from the abyss, it was called Blessing of Sin. Two powerful spirits/demons dwell inside the necklace, Nyx, The Goddess of Darkness. Leviathan, the former Queen of Hell.

You were behind Lucifer, staying on guard. Every demon dared not to set a foot close. They knew who you were, you had the title "Guardian of the Abyss," and everyone knew that. So when Lucifer arrived at his destination, the spirits inside your necklace sensed danger, and your necklace glowed, Nyx and Leviathan spoke in your head, warning danger. You told them it was fine, just stay on guard. Then Lucifer spoke in a serious tone.

"So, Mammon, do we have a deal?"

You heard that name... the Sin of Greed? What would the actual King of Hell need from a Prince?
