"I win. So, I win."
Without Dean there to hold him back, Sam gave Lucifer his consent to be used as his vessel. Lucifer rose to his full potential, and the world was powerless to stop him. His Croatoan virus swept the planet and many of its inhabitants along the way, but there is still much work to be done.
From misguided humans to the demons he created and even some of the strongest creatures in existence, many have allied themselves with Lucifer in his quest to rid the planet of the plague that is humanity. Some fight for entertainment, some fight for revenge - no matter the reason, they are a force to be reckoned with, and Lucifer's strongest weapons in this war.
Never really tied down to one place, Lucifer's entourage tends to wander the land, leaving chaos and destruction in their wake but never overstepping their boundaries. Though they do not have a camp like Dean's cavalry, Lucifer can be considered their base of operations, as every movement they make is generally orchestrated by him. They are loyal to their leader, and are quick to answer his beck and call.
