Wailing Wind

When this spell is cast, you set up a magical warning system. Choose any kind of area within range that is an exit or entrance to an indoor or underground area of any kind. The total size of the entrance or exit chosen must fit with a 40-foot cube. Until the spell ends, a wailing, whistling wind blows towards you whenever a Tiny or larger creature touches or enters the warded area.

You do not have to be in the area to receive the knowledge this spell provides. The wailing wind will seek you out as long as you are within 500 feet of the target area. The wailing wind has a distinct audible sound that can be heard by any creature, though they do not know what it means unless they are familiar with this spell.
