So the Dunmer could have some quest-lines killing off some abusive Argonians, though it would be related to the Argonians guild, the quest-lines would not acknowledge this. Maybe some comments about those damn Dunmer or something. Here is an example for the Dunmer.
Quest 1. Stop some abusive Argonians from harassing the local Dunmer populace. Intimidate or kill the guilty Argonians.
Quest 2. Acquire supplies for a group of Dunmer to migrate to a new location.
Quest 3. Escort a group of Dunmer refugees out to a camp.
Quest 4. Help nullify any threats to the new Dunmer encampment.
Quest 5. Get permission from the Jarl to allow the Dunmer to possess these lands.
End result. A small village of Dunmer refugees that is self sustaining and can protect itself from outside aggression to some extent. The have unique Dunmer equipment for sale and one of the Refugees gives you a Dunmer weapon that was passed down in his or her family.
Thoughts? Obviously this could apply to all races and there is no racial lockouts, Just for fun. Also obviously it is way to late to put it in Skyrim but maybe mods? Or the next game. Just want to see if people like the idea.
