Asmodeus, prince of darkness, found him wandering on one of the Underworld's rocky lava pains and couldn't resist to attack the nomad demon with a cold attractive face. He planned to kill him but faced the unexpected resistance. He was so surprised by Magnuse's thirst for life, that spared the demon and took him to his palace to make one of the closest servants in future. Centuries after their first encounter Magnus will be called the prince's dog or the royal slut behind his back. Most or the royalty thinking he gained his favor sharing the bed with the Asmodeus or even Lucifer himself. Who knows what the truth is.
