A question about a book...

[Mudbill]

I would say highly unlikely. Not only would that put unnecessary pressure on the community, but they'd get nothing in return for doing so. If anything, it would be positive promotion.

However, I can't say that for sure. Had it been a bigger company, I would be wary, and so the possibility might always lurk, unless the book is released under fair use (and abiding by fair use's requirements). I'm not 100% sure if this qualifies as fair use considering it's a piece of FG's original lore that you're incorporating.

I think a big factor is whether you plan on selling this book or releasing it for free. If it's the latter, you're much safer, but if you plan on making money off it, FG might have a say in the matter.

Those are my two cents anyway.
