Etherealness

Step into the Border Ethereal for the duration. You can move there and perceive the plane you left in gray tones out to 60 ft. You can affect and be affected only by creatures, objects, and effects on the Ethereal Plane. When the effect ends, you return to the corresponding location or nearest open space.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
