Faction seller?

This has been bothering me for some time. With my first character i brought into Cantha i remember a Kurzick NPC that sold faction but i cannot find anything on that NPC anywhere. Any help?

There is no such NPC, what you are remembering is the Kurzick NPC that said "There is rumor that certain unscrupulous individuals will even sell faction for gold!" Note the word rumor. The only NPC's in the game the deal with faction directly allow you to give it to your guild or allow you to trade it for jadeite/amber.
