Are mythologies from fictional sources on topic?
- Questions about the Old Gods of the Forest from Game of Thrones?
- Questions about the Nine Divines from the Elder Scrolls series of video games?
- Etc.
I'm thinking no, but I thought the question ought to be asked. We could ban these questions entirely, or we could just have a required tag fictional.
Pros: Widening the site scope could drive more traffic. Both Game of Thrones and Elder Scrolls games are very popular, for example.
Cons: these are obviously made up from some writer's mind, not actual mythology.
