Apollyon
Soul Collector
This is a Very Vague idea that could possibly Flourish depending on how much Interest this gets and what not.
Course It won't be Dark souls Directly as you can see from it not being categorized as Fandom but it will have very similar concepts & Design.
Imagine it as a Very Bleak & Dark fantasy genre Rp.
I'm open about suggestions and getting help planning the Lore & Plot.
