Bind Spectator

After casting summon spectator, you cast this spell to bind the spectator to protect a non-living object of your choosing. The spectator must guard the object to the best of its ability. The creature doesn’t follow your commands, but it won’t attack you or any creatures of your choosing and allows you access to the object.

The spell ends upon the spectator’s death, after 101 years, or if the object or location is removed or destroyed.
