While seeking advice from the Company of Heroes on how to best confront the primal Titan, among the many errands they task the Adventurer in preparation for a banquet at Costa del Sol is to obtain cheese from Brayflox Alltalks. Brayflox has a problem though -- her longstop is currently occupied by a dragon named Aiatar, and he isn't willing to share it with goblin migrants. The adventurer must clear out Brayflox's Longstop to proceed with the story.
In the Patch 2.2 quest "Curds and Slay," it is revealed the Illuminati has besieged her longstop, intent on confiscating her cheese recipe. The instance Brayflox Long (Hard) involves driving out the Illuminati military to protect the cheese recipe.
Brayflox Alltalks is encountered in the Dravanian Hinterlands, having an altercation with the Illuminati (again over the cheese recipe). The Warrior of Light, Alphinaud Leveilleur and Y'shtola Rhul help her drive off the assailants so she can visit a friend in Idyllshire.
