Aurelia, my Volkihar OC, since Dawnguard is coming to the PS3. Alternative background: [link]
Since I haven't played yet, there might be some errors / slight differences in the outfit. It's hard to get references while avoiding spoilers. Used some basic screenshots plus some fan-art to get it as close as possible. Mainly it was the colours, since stuff like the cloak ranged from black to a pale brownish grey in different light / different screenshots. Unless one was modded. Idk.
Anyway, I have Aurelia planned to use daggers and some magic, though I haven't decided what yet, given I've yet to play her. Looking forward to the DLC. Used a reference for the pose, too.
Aurelia (c) Me Volkihar, Dawnguard, Skyrim (c) Bethesda
Since I haven't played Dawnguard yet, I wouldn't know. I'm on PS3 and still waiting for it to come out, so I don't know anything about Serana apart from her looks. The outfit is the same as Serana's because that's what all the Volkihar wear, and I know you can get to wear it too if you become one. Other than that, though, I'll have to wait and see as to how similar the two characters are once I get to play.
