An original world, or one (or several) you already love: type fate/stay night, kakegurui, steins;gate, harry potter, star wars…
How close to the source?
Premise - optional: leave empty and the Forge decides
Anything else? - wishes the Forge should respect
Who is in it?
Add characters from existing media (their canon look, age and bonds come along) and original ones. Adding a canon character suggests the people around them.
Names come from the Danbooru art database (so the art model knows them). Anyone not found is kept as "not verified".
What should it feel like?
Every slider has named stops: the Forge reads the words, and the narrator keeps following them while you play.
Genre mix
Who are you?
Your character. Leave anything empty and the Forge decides.
