Stonedoor is a castle along the Wall, abandoned by the Night's Watch. To the west lies Greyguard and to the east Hoarfrost Hill.
Lord Commander Jeor Mormont plans to re-garrison Greyguard, but Qhorin Halfhand advises Stonedoor instead, due to Greyguard's poor condition.
Jon Snow is with a group of wildlings who attempt to climb the Wall between Stonedoor and Greyguard.
Lord Commander Jon Snow gives Stonedoor to Soren Shieldbreaker to garrison and settle his own people. Borroq is scheduled to join them.
