Just wanted to pop in here to offer my support. I'd love a 'Mystery' tag. Also something between 'medieval' and 'modern' would be great as a time period tag.

We have a historical tag but I do agree that maybe it'd be worth expanding upon since we have "medieval" and "modern" already as tags. Personally, though, I'd keep any new historical tags focused on major periods of history, such as but not limited to:

- Napoleonic
- Victorian
- World Wars
- Cold War
