Astral Citadel

Create a fortified astral refuge overlapping your location. Creatures of your choice in the emanation have resistance to psychic damage and cannot be possessed, magically put to sleep, banished, unwillingly teleported, or have their souls displaced unless they allow it. As a bonus action, you may move one willing creature in the emanation up to 30 ft. to another unoccupied space in the emanation as its spirit is carried by silver cords.
