go out, enjoy the good weather!! 
yeah argonians live in black marsh, and I like your suggestion. I like them all, you can make the buttons (it's not a problem though, I can make buttons too, I've made tons of them earlier).
we have only breton and dunmer left then... For bretons, if you find something medieval, a crown and a sword, or something similar...
For dunmer I have no idea
maybe a volcano?
For orcs, I gave them massive production and units production bonuses (mostly) in the capital, and made their starting position, too, production powerhorse; plus I'll make their leader very aggressive; so they will produce huge armies and go to war to conquer cities. I'm thinking, lore-wise they didn't fare well at all; and had just one city which got destroyed twice. So, if AI-controlled orcs don't succeed in most of games, that's not that bad. For a human player, though, it will present a challenge.
I need to test how will they fare; if they're too bad, I'll go with your idea
