Well, not every House has to have a Valyrian sword, so I’m a little hesitant. I don’t think the Teagues would have had one, and if the Justmans ever had one it probably would have been lost with Bernarr II (although I like the name Balance). As for House Gardener, I like the idea of Longthorn (maybe Leo Tyrell nick-named himself after the famous blade?) – hat tip to @warsofasoiaf for that one.
