You aren't able to join them, but there are quests for them. They're in a place called hollow hill, north west of cleganes folly in the westerlands (other side of mountains)

Isn't the first quest bugged though? If I'm not mistaken you have to change the status for The Tickler with something like Morgh's editor before starting a new game, in order to complete the BwB quest.
