I am envisioning a scenario where you create a 15 x 15 room or building viewed through a door to have an interior.
Does the object created by Silent Image have to appear as a solid object? Or could you put a doorway in the side, and have someone walk inside of what seems to be a small cottage (Empty) without realizing it was an image until they attempt to touch/interact with something? (Place their hand on a wall, or attempt to climb stairs)
Silent Image Description:
You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 15-foot cube. The image appears at a spot within range and lasts for the duration. The image is purely visual; it isn't accompanied by sound, smell, or other sensory effects.
The possible duplicate in question : Can you create an illusion of empty space?
This post asks whether you can create an image of air around yourself so that you would seem to be invisible. I am asking if instead you can create an image which has an inside. I don't want to hide anyone on the inside of the cottage.
