House Dunsley was an ancient Sigorian Kingslander noble house established in the Sixth Era and legally went extinct around the time of the Dragomyr invasion of Andoras. Around the time of the Dragon Wars in the 510s BC, they began to fuse with several other houses by merit of marrying into them; most of them are similarly-fated Kingslander houses on the same social scale of them. House Dunsley is dead in name, but their lineage lives well on in the northwestern Kingsland and in the Moonlyt Peaks.
When House Dunsley was a recognized House, they retained lands to the west of Brand, near the border of the Duchy of Morano in nearby Thyllanor. This land is now administrated by another house that claims Alettonic heritage, a heritage relatively uncommon in the 350s AC.
