Oak Dancer is the leader of a wolf pack of a good dozen wolves in Tel'aran'rhiod, among them Boundless, Morninglight, Sparks and Whisperer. She got the name Oak Dancer because of the way she scampered between the saplings as young. She and her wolves call to Perrin when he is there and help Hopper teaching him. Oak Dancer grieves when Morninglight is killed by Slayer. Later Oak Dancer, Sparks and Boundless are trapped in the dreamspike, but Perrin and Hunter rescue them. (ToM, Ch. 4, Ch. 18, Ch. 24, Ch. 28)
