I've made a mod which contains imitated Gawnguard catsle and Volkihar catsle.

So even if you are on the DG side, you can still adventure/stay/talk in the Volkihar catsle of mine. And vise-versa if you are on the Volkihar side.

Also, I put almost all of the weapons/armors (Dawnguard's/Volkihar's/New falmer's/Moth priest's/etc), so you can just pick up some from the storage of the catsle for a trial. I put merchants selling these items, though. ^ ^

Anyway, I made this mod as a temporary GD location mod until someone makes nice Location mod consisted of the GD contents kit. ^ ^
