Alright, I've been taking a look at some things over at TIL, and I have some questions.
First off, is Hammerfell split into different regions with different rulers, sort of how the Counts and Countesses work in Cyrodiil?
If that is so, then each region would have a different military, correct?
What are the names of these leaders? If in fact Hammerfell is split up into different regions.
What is Hammerfell's relationship with Cyrodiil?
I read the link provided by Nalion, and I think I can answer some of your questions.
1. Yes, Hammerfell seems to be split into different regions with different rulers. It doesn't seem to have a single monarchy like Morrowind.
2. I got this from the PGE. Due to the divisions within Hammerfell society, the Redguards seem unable to form a cohesive fighting force (though I believe the Kingdom of Sentenil has a standing army). When the Redguards go to war, they are probably something along the lines of a well-organized, very skilled militia.
3. Do some TIL to find out who the premier leaders of Hammerfell are. I know a lot of Daggerfall books talk about the Sentenil royalty.
4. On the relationship with Cyrodiil, it seems to be split. The Crowns I think might not like the Empire all that much where as the Forbears seem to respect Cyrodiilic culture.
