Arel Malevin is an Asha'man from Cairhien.
He is wide and short.
He Travels with Logain Ablar to Tear to find Rand al'Thor. He takes part in the battle against the Trollocs that attack Algarin Pendaloan's manor. He is then part of the group that burns all the bodies left behind afterwards.
During the Last Battle on the Field of Merrilor, Arel is one of the few men that stays with Logain after he sends groups of Asha'man and Aes Sedai to try to find the lost Seals. Logain affirms that it was a fortune that at least some of his men as Arel Malevin had been absent when he was captured by Taim. We can also suppose that Aislin Sedai was with Arel and so she escaped the capture and the forced conversion to the Shadow.
