Veiled Haven

Walls of magical force spring into existence around and above you to form a 15 ft. cube. The walls appear to be shimmering, silk veils of any color you choose.

Despite its exterior size, the cube's interior space is a larger extradimensional room, the volume of which is 30 cubic ft. The atmosphere inside the room is comfortable and dry, regardless of the weather outside. You can command the room to become dimly lit or dark. Creatures and objects within the room once you cast this spell can move through it freely. All other creatures and objects of your choice are barred from passing through. The cube is opaque from the outside as well as from inside the room. Although a creature within the room can use an Action to pull at the veiled walls and peek through to the outside. Doing so does not allow outside creatures and objects to pass through. 

Spells and other magical effects can’t extend through the cube or be cast through it. 

The cube remains stationary for the duration and dissipates if you leave the room within, ending the spell. The spell also ends if the room within includes more creatures and objects than it can contain. Once the spell ends, all creatures and objects inside the room are magically shunted out of it and into the nearest unoccupied spaces that are safe to stand in.
