A deafening silence ripples out from you, washing away all color and form from the landscape. The area of the spell becomes a level, flat white, brightly lit recursive plane, meaning that an object or creature that leaves on one edge will enter from the opposite edge in that same motion. The area of the spell becomes completely blank and free of any walls and objects or any kind of terrain that were in place before the cast, and all creatures become unable to benefit from partial concealment while inside the spell and have disadvantage on Stealth checks. Creatures can leave by teleporting(any line of sight rules would still apply for the teleport), though if the caster leaves the area of the spell it automatically ends, even if they maintained concentration.
Creatures outside the area of the spell treat it as if nothing had happened and all affected objects and creatures were not there; they do not have line of sight or effect to anything inside the spell(though they are aware it has been cast). When the spell ends all affected objects and creatures return to the space they occupied before the cast, or the nearest available space.
