Kell is a castle located in the Stormlands. It was once the seat of House Keller, until it demolished during the Fourth Border Wars. With its lands unclaimed, Lord Trevyr Blackgard and Lord Jothos Harrigon decided to grant them, and the ruins of Kell to House Droft, a cadet branch of both their houses.
The castle of Kell served as the ancestral seat of the Kellers for many centuries. While not as grant as Harrenhall in the Riverlands, it was known to have stable foundations on par with it.
