Word spread fast, if you knew where to listen. Circles of people became aware of his presence of the mortal plane, and they either went into hiding or foolishly came after him. The first group would have the longer survival rate.
The second were mainly hunters, which Lucifer had to admire as warriors going into a useless battle. They would not win, but they tried. He sighed, watching them fall and knowing that it was their fate. It would soon be all their fate.
It was also the demons who learned quickly. The ones who had faith in him, in knowing that he was going to bring an end to the world that had hurt them and made their choices easy for the path they had taken. He was their salvation, and as long as they did what he asked, he would give them that.
As the weeks went by, Lucifer came into battles with his brothers in which he had his fallen brothers rally to his side, and fiery swords met lightning and clashed in battles of pure light that destroyed towns and cities in the flash of an eye. They were trial battles, and Lucifer was waiting for the real fight that would bring about his victory.
He was waiting for Michael to come.
He was getting bored, and had been unable to convince some of the more noble of his brothers to join in his efforts. After all, what had these humans done but strip the beauty from the earth and make it a pit of the worst sins and vices that ever been created. Now all that was left was the final battle. If Lucifer was able to defeat Michael, he would be able to prove God wrong and be able to take his army and regain his place in heaven.
He had not been able to feel any of the Winchester family. The angels had wrapped them up quickly, as well as anyone else that would be a way for Lucifer to get Dean out of hiding. That was his last obstacle, and one he wanted to deal with quickly.
He was a patient man, but there was a difference between waiting for the inevitable, and waiting for the outcome. This was going to happen, that he knew. How long was he going to be made to wait? How long was God going to let his precious human race suffer while Dean made his choice?
It made the taste of the human agony all the more delicious, knowing that God was letting them die to give Dean his chance at free will. Oh Dean, trying to help people and look at the pain God is causing on your behalf. That would make Alistair so proud if he could see it.
The one day, just at sunset, Lucifer felt it. The shift of power in the Heavens, and he closed his eyes to feel the beginning of the rain falling to quench the fires that surrounded him from his latest victory. He turned slowly, and through Sam's eyes he saw his brother standing there, watching him.
And he couldn't help but smile in greeting.
"Hello, Dean..."
The smile grew on Lucifer's face as his demon army stepped back out of range, their senses picking up on the inevitable catching up with them.
"... or should I say... Michael."
