What constitutes 'equal representation'? Or even a faction?
Does each Dalish clan and each alienage get a vote? That would run into a problem if there are more small tribes than big alienages.
Do the Dalish and the City Elves each collectively get X votes? If the City Elves significantly outnumber the Dalish in population, that wouldn't be proportionally fair to the city elves.
Would significant groups of importance like, say, Briala's eluvian faction get a vote? How about an alliance of elven merchants who are key bankrollers of the project?
What would be the rules against sub-dividing to claim more seats as more factions that are simply aligned?
The three factions are so: City Elves, Dalish Elves, and Tevinter Elves, since those three groups have lived apart for a long enough period of time to have developed their own cultures. I'd include the Qunari Elves, but they wouldn't really be interested in this new homeland since they have found their place in the Qun.
As for votes, each faction gets equal say to avoid one culture gaining dominance over the others. Decisions could be met by a majority vote.
Small factions like Briala would be more like lobbyists.
What constitutes abuse? The Dalish religion/culture regularly compares the Human culture to a disease, and the ancient Dales appears to have extended that belief to Andrastianism as well. In a zero-sum scenario in the existence of the other is considered a harm, what gives?
Your example would be considered an abuse since it is insinuating the elves that support that culture that is being insulted are detrimental to the society.
Basically the stance will be a "live and let live" type scenario, as in you can believe whatever you want as long as it doesn't hurt others. By hurt, I mean physical as in mugging them, mental as in insulting them, or spiritual as in forceful conversions.
Wouldn't a key prejudice be the practical disenfranchisement of non-elves, since you reserved representation for your leadership council to elven factions?
Also, what's the policy towards half-blood elves? Do they count as elves, or humans?
That's a good point about non-elves. If they have significant numbers in the nation, they get a seat in the government as well. Below that they would be like the lobbyists. And predjudice against them would be illegal as much as it is to other elven factions.
As for elf-bloods, if they identify as elves they are recognized as such.
Well, that's easy. Even the Dales had diplomati and economic relations, even if that relationship was 'none, or else.'
What kind, with who, and what are the goals of foreign policy?
Peaceful preferably, with at least the neighboring nations if not all, and the goals are the continuation and prosperity of the nation and those who call it home.
