Kerb was a young chandler's apprentice.
Kerb was a spindly boy and had light hair. He had burns on his hands due to his occupation.
He was heavily Compelled by Graendal. He was captured by Nynaeve al'Meara in Bandar Eban when she goes to search for Milisair Chadmar. Kerb was responsible for the poisoning of King Alsalam's messenger and Lady Chadmar. Rand al'Thor ordered Nynaeve to dispel the Compulsion weave to find out Graendal's location. Once that was done, all that was left was a useless husk. Through sheer will power, Kerb managed to whisper out that Graendal was at Natrin's Barrow. He then collapsed and died.
