As you move around Lusternia, you will encounter doors that bar your way. Doors may be closed or open, locked or unlocked. Although it may seem odd, they may be locked open (imagine a bolt lock that has been locked with the door still open). In order to open or shut a door, all the locks on the door must be unlocked. The following commands are used to deal with doors: OPEN DOOR <direction> Opens a door in a direction. CLOSE DOOR <direction> Closes a door in a direction. UNLOCK DOOR <direction> Unlocks all the locks you are capable of unlocking on the door in that direction. LOCK DOOR <direction> Locks all the locks you are capable of locking on the door in that direction.
