Hello,

Bethesda trademarked the name : Redguard. It could be the name of the next ES game taking place in Hammerfell. I have a very strong feeling that we will be seeing Hammerfell next with its beautiful cities and the Alik'r desert.

A picture I found on google of the city of Rihad.

Hammerfell would be my least favorite place tbh... but heck, it's a TES and they simply can't make it more generic than Cyrodiil. Or can they?
