The Thistlefur tribe (or the Thistlefur Clan) (The Beast Within 34) are a tribe of hostile corrupted furbolgs who reside in Ashenvale. They reside primarily in Thistlefur Hold in the westcentral area of Ashenvale and in Thistlefur Village to its south. They are viewed as a annoyance by the Horde since their village blocks the way to Splintertree Post, giving the Alliance an extra expansion path. They were corrupted by the Idol of Remulos until it was cleansed by Broll Bearmantle, thus freeing them from its corruption.
