Spatial Fold

You fold spacetime around a 10-meter diameter area, creating an inaccessible pocket that exists outside physical space. The affected area ceases to exist in the physical world - terrain adjusts naturally around the absent space and creatures cannot occupy it. Creatures inside the fold can see the outside world as if through a shimmering barrier but cannot leave until the effect ends or is dismissed. Time passes normally inside and outside. When the effect ends, the space returns as if nothing happened there. The fold is imperceptible from outside - Detect Magic reveals a faint spatial anomaly.
