For example:  

[This question](https://mythology.stackexchange.com/questions/154/who-made-thors-hammer) uses the tag [thor](https://mythology.stackexchange.com/questions/tagged/thor "show questions tagged 'thor'") along with the tags [norse](https://mythology.stackexchange.com/questions/tagged/norse "show questions tagged 'norse'") and [deity](https://mythology.stackexchange.com/questions/tagged/deity "show questions tagged 'deity'").

[Another question](https://mythology.stackexchange.com/questions/10/f%C3%B3lkvangr-and-valhalla) uses [valhalla](https://mythology.stackexchange.com/questions/tagged/valhalla "show questions tagged 'valhalla'") & [folkvangr](https://mythology.stackexchange.com/questions/tagged/folkvangr "show questions tagged 'folkvangr'") along with [norse](https://mythology.stackexchange.com/questions/tagged/norse "show questions tagged 'norse'")

So the concern is, doesn't the mentioned tags such as [thor](https://mythology.stackexchange.com/questions/tagged/thor "show questions tagged 'thor'")and [valhalla](https://mythology.stackexchange.com/questions/tagged/valhalla "show questions tagged 'valhalla'") already fall within [norse](https://mythology.stackexchange.com/questions/tagged/norse "show questions tagged 'norse'") ? Should we allow tags for distinct elements which already fall under the main cultural tag?
