Sparks is a wolf in Oak Dancer's pack who calls to Perrin in Tel'aran'rhiod, and the wolves help Hopper teach Perrin. Sparks and the other wolves in the pack grieve when Morninglight is killed by Slayer. Later Sparks, Oak Dancer and Boundless are trapped in the dreamspike, but Perrin and Hopper rescue them (ToM, Ch. 4, Ch. 24, Ch. 28).
