You misunderstand me Supremacy. What I meant was the fact that it is difficult for elves to pass through districts. You enforce that and you hunt impures within those districts. It is in relation to this post, I think.

Forbidding a dark elf to have a home in the wood elf district is fine, but you should not bar their entry, or discourage other high elves from roleplaying with the rest of the elven populace.
I wouldn't ask for something as silly as a 'Impure district', but veiled under the guise of a 'Trading district', where this zone can be open to outsiders to walk in freely, and a small melting pot area like a market place. All subraces maintain their uniqueness, and new players can experience the elven culture before being fully integrated in their respective district.
Basically something like this, your own districts in the surrounding or whatever, and then a place for all races to enter freely(The trade district/General district). A few taverns to not permanently house people, but to act as a transition point. Maybe one or two exceptional guests can stay there indefinitely? I dont know. High elves can still act superior within their own walls, but have a excuse to rp with others outside those walls. Same can be said for the other 2 elven subraces.
Anyways these are gameplay designs. I have no knowledge on how rp will progress, but this is what I would like to see.
