House Dun is a venerable, if somewhat shadowy institution with its roots in the bucolic Dunsborough. Its business is the slave trade, and as that trade is slowly dying on the mainland, it has created branches for itself in some of the less reputable corners of the world - one such being the incomparable Golden Tether on the islands of Guildereim. The House functions largely under the auspices of the steely Madame Didiane Dun, and does a generally brisk business purchasing, polishing, and re-selling slaves, in addition to offering slave-training services to slave owners.
