What about Redguards? I'm pretty sure nobody wants to break bread with them. They are probably one of the worst races in all of Tamriel. They don't give a crap about anyone, most are likely to despise you for being in the way, and to top it off. Redguards aren't even peaceful. Endless conflict can be seen throughout their histories, and not one Redguard I heard of has ever been an advocate for peace.
How is anyone going to see eye to eye with them?
Yeah, endless conflict pretty much sums them up.
The thing with them though is that they've never shown interest in expansion. They've never invaded another province (excluding the original Warrior Wave, of course). And they also don't have a singular race that they want to eradicate. So just stay out of Hammerfell and you'll do fine. The Crowns will continue to not give a shit about you and keep to themselves. The Forebears, who probably became less trusting of foreign powers after the Great War, may want to trade a little bit, but that's about it (but like I said, the Forebears could've become less open to foreign influence). That's pretty much all the foreign interest they have.
What about the Orsimer, whom they belittle with reenactments of by-gone battles? Yeah, they don't invade other provinces. Poor old Orsinium eh? Who got sacked by an unknown force in the 4th era. Who else could this force have been if not the Redguards, and Bretons?
With the latest invasion from the Dominion I am certain they have full interest in wanting to retaliate against the High Elves now.
The only reason why they can't expand is because half Hammerfell is always after the other dreadful half.
There is going to be a lot of trouble trying to convince Reguards to live in peaceful harmony with the other races alright. You said it yourself, the Forebears are not welcome to any foreign influences, and the Crowns don't give a shite about anyone other than themselves.
I can't see it happening.
Admittedly I did forget about Orsinium. The first Orsinium was a very aggressive province. They were justified in destroying it. Nova Orsinium was the peaceful one that didn't deserve to be destroyed and in fact is probably one of my favorite political stories in TES, but I won't go into that right now.
Regarding the plays, I never said they aren't a people that revere their warriors to the point of almost worship; I said they don't want to eradicate any of the races. And they don't.
No one can say what it'll happen. Maybe they'll join the fight against the Dominion, maybe they won't.
I did choose my words carefully there: they've never shown any interest in expansion. I'm not saying they don't have any interest, but we have never seen any. Which more than we can say for a majority of the races.
You know, I find that what's going on with the Gray Quarter to be as much the fault of the Dunmer as the Nords. Look at Riften! The different Races there get along quite well. Why is that not the case in Windhelm? "Because Ulfric is a super racist!", right? Ha ha, WRONG!!! When the other races were allowed to take refuge in The Rift, they were told they were expected to work hard. When the Dunmer were allowed into Windhelm, no such expectations were set. This inevitably led to most of the Nords there viewing the Dunmer as a race of lazy bums. The treatment the Dunmer got only grew worse from then on out. If they had worked hard even though they weren't expected to, who knows? It doesn't help that the Dunmer are practically trying to turn the Gray Quarter into a little slice of Morrowind. The Nords consider that an insult to their city, their culture, and to their heroes who built the place.
