Arcane Window

You cause a magical window to appear on a flat surface you can see within range, such as a wall, floor, or ceiling. This surface must be 1 foot thick or less. For the duration, you can see and hear the location immediately on the other side of the surface as though you were looking through a small window set into it. Objects not permanently fixed to the surface, such as furniture, curtains, or hangings, may obscure your view depending on their position on the other side.

A creature that can see invisible objects perceives the window as a small luminous pane hovering against the surface.
