Primals. While sometimes mistaken for gods, they are beings created by Astrals to represent different aspects of reality. Their appearance varies, but they often are capable of manifesting some kind of humanoid form to interact with the mortals. Their size also varies as they have some control over it, often being depicted as massive but being able to scale themselves down, similarly to interact with the mortals.
If the character you're looking for doesn't exist yet, feel free to create the option for them yourself. You are not required to write the introduction blurb if you don't want to; just have the page be there before the scenario you're introducing and I'll get around to it eventually.
The next page will provide some info on the character along with some choices that function as starting prompts. After that, the story will start proper.
