[Elmo]

Just a point about what the White Council had to face in Dol Goldor.

After reading about the fate of Elves after they die in Morgoth's Ring it's clear that Sauron wasn't called the Necromancer for nothing. He controlled the spirits of evil Elves who had refused to enter the Halls of Mandos. I'm guessing Dol Guldor would be an abode of many of them. What form would these demons take? I'm guessing Galadriel would have to use Elvish magic to combat them in some way. I don't think even without Sauron there you could have taken Dol Guldor just with a mundane force.
