One Thing I must say before jumpin’ in:
1. Watch Slayers Next, the second season of The Slayers TV series. Subbed or dubbed, doesn’t matter. Don’t worry about the first season, you can always go back. Major spoilers from the last two episodes are coming. This is your only warning!
Let’s talk about the Lord of Nightmares.
The Golden Demon Lord, L-sama, the Sea of Chaos, she has many names. In the fantasy world of Slayers, the Lord of Nightmares sits at the top, above humans, above dragons—demons, Gods, she is a creature in a class by herself. I’m talking next-level cosmic stuff here. So, why do I think the Lord of Nightmares is awesome? It’s not like omniscient beings are rare in fiction. The answer to that lies with what she is as well as her interactions with others.
Being a fictional world, the Lord of Nightmares fits quite comfortably within the Slayers lore. In fact, the magic and overall hierarchy of world building in Slayers is some of the best I’ve ever seen. I encourage anyone interested in magical fantasy to check out Inverse.org and read up on the detailed word of Slayers.
