Sneaking wood-elves into Neriak

[Mentathiel]

As a few players have discovered, I play a rogue who likes going into places she shouldn't be. My next goal (at lvl 18) is Neriak because... just because. The only issue is that wood elves and dark elves do not mix. When I looked into illusion items, the dark elf masks are NO DROP and the one still in the game drops from a lvl 35 undead who sees through hide and sneak. I plan to do the red wine quest to push up my faction once I get in, but living long enough to do the hand-in seems to be the challenge.

Is it just going to be a case of sneaking in and doing the hand-in from behind? Am I just wasting my time sneaking into Neriak?
