Adding a sanity aura to specific biome or building

[Jaspers]

I was working on my character for Dont Starve Together and I came across an interesting factor that would go along with the character well, and that is to get sanity from a specific biome or tree. Right now I am wanting my character to be able to get sanity off of Birchnut/Deciduous trees, or if it is possible. To be able to get more sanity from being in a specific biome. I don't think that there would a prefab or code already set up for that considering that this is not a function that any other character has.

If anyone gots any advice or information, please share.
