I'm sure the Quarra can travel to other provinces, but it would be much taxing since they cannot walk in sunlight. But remember if a member of the Quarra met with a Volkihar, things would be difficult. Many clans have different cartel agreement and feeding terms, i.e. "Don't feed on my boundaries and we won't have a problem" but since the Volkihar is known to be highly paranoid and cruel, I doubt they will tolerate a member of a different clan other than themselves. Don't think a Quarra can go to Cyrodil without gaining an immediete death warrant upon being discovered by the Order. We all know the Order don't take **** from other clans.
Gah!!! ya I was gonna have them in Cyrodil since thats the only place I know, that and the places from Morrowind but I don't think I have played a game yet where the Quarra were located....I think lol tho than again if she goes to Skyrim than atleast she has just as much issues u know? lol
damn i really need more info on these ones to, all i got is that they are more aggressive but other than that no idea if they look any diffrent or if they are able to be in the sun light if they feed enough
