Boesild Aerasumé was Alustriel Silverhand's eighth son. He was known for being the most pragmatic of her sons. Boesild was also the Moonstars' regional agent for Luruar and the Evermoors regions and the only one of Alustriel's children who got on well with Khelben Arunsun. The rest only barely tolerated him for their mother's sake.
