"I do so wish that my work didn’t make such a wretched mess. At least the worms clean it up."
There are different sorts of demons in the world. Some are indistiguishable from normal people. Some are a little different, but pass initial scrutiny. And some are much more monstrous.
Every Court needs its servants…
"Such a delirious monstrosity would never be allowed by the Unconquered Sun! It is the spawn of the hell-fiends sent to do their foul work! It and those that brought it into being must be destroyed!" - Lux Sialos, Knight of the Shining Crusade
"Such well behaved children… never a word out of them and they do just as they’re told. They seem so pale though, I wonder if they’re sick…"
"They come with the mist, and fight to protect us. Protecting their people meant so much to them that they kept fighting for us after they fell. Count yourselves blessed that the Company of Stars watches over us."
- Mylnes, Ethalani Elder
“They just keep coming. You cut one down, two more are right behind it. We can’t win, they just keep coming…”
- Unnamed soldier, overheard at the battle of Caele Aran
“Why should we send our young men off to die when we can manufacture the War Walkers for the same purpose?”
- War-Theurge Ceylon of the Fourth Dynasty Army
“We beg the protection of the gods. Of Deneth, divine father; of Larisa, queen of the heavens; of Mynis, guardian of the gates; of Tychis, master of secrets; of Desha, she who protects. Grant us safety from the sons of the devourer of worlds. Grant us protection from the Jandoshan.”
- Ethalani prayer
“It is said that the shadows hold many dangers, and that is true. I am one of those dangers.” - Saja Jyn
“It is not merely the things lurking within the shadows that you must be wary of. Sometimes, the shadows themselves can be your enemy.” - Moraten Li
What can be more maddening than the eternal sobbing of a child whom no one can comfort?
If you want to add a "supernatural" touch to your campaign, define the rules of magic and the universe. Make your players comfortable with those rules. Then your new supernatural creatures must then break those rules.
