Iralin is a willowy Domani man who was uncharacteristically clean shaven for a Domani. As Rand is leaving Bandar Eban, he tells him that all the food in the stores and the Sea Folk ships has spoiled and makes men sick to eat it (TGS, Ch. 42). After Rand leaves, he is forced to blockade the harbor to prevent people from stealing the food ((ToM, Ch. 26). When Rand returns, he shows Iralin that most of the food is fine, and that it was just the hundred sacks Iralin checked that were corrupted. Rand names him to the Council of Merchants (ToM, Ch. 26).
