Cakeverse
A fantasy setting with various rules depending on the author or creator. The key feature includes individuals born with or manifesting secondary genders and constitutions that define people between:
Forks – People who can taste the flavor of cakes. Eventually, after multiple interactions with Cakes, their tastebuds will be rendered useless, and they will only be able to taste Cakes. This leads to cannibalistic tendencies.
Cakes – People who exude specific flavors from their flesh or body fluids. Can go their whole lives not knowing they are Cakes until they interact with Forks.
Normals – People who are neither a Cake or a Fork.
