The Faceless is a truly awesome creation. Since none of my players took one, I created a Faceless NPC, Hush Hush, for my online game. On a whim, I also made him mute due to a minor knife fight incident, so he was the faceless, voiceless enforcer of the Hardholder. And then he got fired (technically, tied to a table and offered in barter) because his new mask, that he'd stolen, gave him a conscience.
And so far everybody who's tried to examine the mask through Weird means has botched their roll and found themselves on or near a giant, mask-shaped island in shark-infested waters. It's been rather awesome, although I also think it's built Hush Hush into this Big Mystery of the setting rather then the poor bastard that I originally intended.
