Elwin is an older male Fey who has served as the Quartermaster for the Trailblazer Association for the past fifty years. As guild members return from the Eldritch Blight, it is to Elwin that they report what they find.
His job is to confirm if any items are magical. If so then the Trailblazer Association pays the finder for the item and adds it to the guilds inventory. The Quartermaster will also exchange gems for gold. Finally guild members can often requisition items for their adventures from the Quartermaster.
