Lucifer has burned up all of his emotions and his energy for the abyss and his people, and his family too, and he's just a tired ruler that refuses to stop.
"Do you wonder why the sun is so bright, why it reigns as the most majestic in the sky? Because it’s burning itself up, it’s burned up all it has to give, and like the sun I too have burned up all that I am."
"so that I may give my people what it needs. I sit on a throne with a crown upon my head that grows heavy and crushes me, it becomes harder to breathe each day that I give and take nothing for myself."
