The Walking Dead introduced some new characters from yet another community in "The Key" when Maggie (Lauren Cohan) & co. met them and heard their unusual request. In exchange for some vinyl records (so hip), the emissaries came bearing the commodity of knowledge. The information they gave will not pay off until the current war is over and civilization can start to be rebuilt, but down the line, these mysterious folks will return. It was an intriguing introduction, but the episode left some crucial information about them unanswered; namely, where are they from, what do they really want, and what role will they play in the future?
