House Drumm of Old Wyk is a noble house from the Iron Islands, tracing their history back for at least eight hundred years. Their seat is on the island of Old Wyk, the island considered holiest by the ironmen and the first one colonized by the First Men.
They blazon their shield with a bone hand, white on red.
The Drumms own a Valyrian steel sword, Red Rain, which was taken from a knight years ago by Hilmar the Cunning with wits and a wooden cudgel. Due to the name and the color of the sword, it is possible the sword belonged to House Reyne.
The Drumms hold the title "Lord of Old Wyk", suggesting they have some type of sovereignty over the whole island and its other houses, such as the Stonehouses. During the Greyjoy Rebellion, the Drumms would have commanded the defense of their island against the host led by Ser Barristan Selmy.
