I'm the demon lord Queen Mortemseeker. I took over the demon thrown after I challenged Marshall lee and I's mother and over threw her power with my own. I had killed her within seconds and was given the crown. I changed the demon realm making it a much better place for demons. I didn't allow death and destruction anymore. Demons no longer had to wait in a line for days to speak with me instead where put on a waiting list based on the urgency of their problem. Everything was great. Demons where healthier and cleaner. The realm was at it's peaceful state once more. The thing was. I myself wasn't at peace in my own mind.
