Prologue:
A descendent of Ignotos Peverell (Godric Peverell) arrives in Westeros around the time of Bran the Builder. He lands on the island of Skagos and after he determines there is no way for him to return home, he decides to make the best out of it. He completely takes over the island, with a little help of magic. He helps Bran Stark build the wall and also builds a bridge between the mainland and Skagos. It is a 150 mile long bridge and wide enough for four carriages to ride abreast. It has a roof tiled with bronze colored tiles that shine in the sun; it's called the Bronzeway Bridge or simply "The Bridge" much like The Wall. The sigil he adopts is a silver outline of a phoenix on a deep blue field. The Peverell house words are "With Bold Nerve We Dare". (Adopted from another HP/ASOIAF fic) House Stark & House Peverell will always have close ties. Skagos becomes a mining, crafting & tinkering kind of region, since the Peverells encourage freethinking. A lot of sculptures and art come from them. They also make fine china with house sigils of course. It is wildly expensive since they have to be hand painted individually. Another item that comes from Skagos that is a "wonder" is the music box, a very high-end item.
