The Daily Grind: What NPCs stick in your memory?

I'm not fond of a lot of the storytelling on display in the Prophecies campaign of Guild Wars, but I have to admit that, against all logic, I was happy when Gwen showed up again. I joked about her, I complained about her uselessness and her irritating habits, but the fact that she turned up alive again always tickled me on some level. When I think about the game, I think of her, and her trials and tribulations stuck with me long after Prince Rurik had all but vanished into memory.

In an MMO with any sort of story, some NPCs are going to stand out to different people. Even beyond the signature characters of a game's box art, incidental figures wind up getting embedded in the consciousness of players. Maybe it's one of the recurring heroes in the City of Heroes tip missions, or perhaps it's one of the more amusing mission NPCs in Star Trek Online. Whatever the reason, what NPCs stick in your mind regardless of their importance or lack thereof?
