Pathway Mirror. This mirror is connected to another one of the same kind.You can speak a command word to activate the mirrors. While the mirrors are active the reflections of them are swapped. You can see the reflection of the other mirror, and the other mirror shows the reflection of this mirror even if the mirrors are on different planes of existence. You can speak the command word again to swap the reflections back.   Additionally, while the mirrors are activated, a creature can travel through the mirrors by speaking a command word and stepping through the frame. Once a creature has passed through a mirror, they cannot travel back for 8 hours.
