Door was a rock-shaping Glider living in Blue Mountain. Her powers were used by Winnowill to open and block the entrance to Blue Mountain via Sending commands. Door remained in a trance-like state for this existence, never moving or requiring sleep. Despite being attuned solely to Winnowill and Lord Voll , Strongbow's powerful sending forced her to open the wall multiple times. It is assumed that during the collapse of Blue Mountain she died and was buried beneath the rubble, unlike her counterpart (male) Door who was saved.
