House Blackwood

House Blackwood of Raventree Hall is an old house from Raventree Hall in the riverlands, one of the main families sworn to House Tully of Riverrun. They once ruled the riverlands as kings during the Age of Heroes. They blazon their arms with a flock of ravens on scarlet surrounding a dead weirwood upon a black escutcheon.

Raventree is located in Blackwood Vale north of Riverrun and the Red Fork. Some Blackwoods are buried in the village Cairns, while others are buried beneath the dead weirwood of Raventree
