With a 15, you wild shape and easily understand what's happening here - you sense the panic and their need to escape. The stampede is heading for the edge of town... to the edge of Thay, right up to the time bubble that envelops the town and then leagues of them crash into the wall, falling. The animals are comprised of all sorts of majestic creatures from centaurs to doxies to shamblers.

For as long as Zelda is willing to watch, they keep trying to break out of the bubble, rearing horns, fists and paws up against it, trying to break free, but to no avail whatsoever. The time bubble refuses to budge.
