I was initially convinced that Pillar Dark was Sauron, but I now realize that his "eye" would probably be singular in that case. You just don't think of Third Age Sauron with a pair of eyes.
So, how about Gandalf stopping the Nazgul from entering the gate of Minas Tirith? The most probable watcher is then Pippin... but it doesn't fit quite well with one of your previous hints.
