The cave of the three-eyed raven is a place located Beyond the Wall. It serves as the abode of the greenseer known as the three-eyed raven and a group of children of the forest who protect it and him. Above the cave lies an ancient and massive weirwood tree with a face carved on its trunk. The weirwood's roots dig deep into the cave and have merged with the body of the three-eyed raven. The entrance to the cave is protected by the magic of the Children of the Forest and prevents wights from entering it, destroying the undead creatures if they attempt to enter.
