Goblin Tunnel

On rare occasions, the Astral Plane can fold in upon itself, creating a tunnel that facilitates travel in the same manner as a normal planar junction - but each end of the junction will open to a different moment in time. Because of both their unpredictability and their rarity, attempts to wilfully make use of these phenomena are impossible for all but the Goblins of the Moon, from whom the Goblin Tunnels get their name.

Any given Goblin Tunnel appears only for an instant, and often - though not always - leads back to the same plane it originated on. On the Material Plane before the Mystfall Goblin Tunnels are responsible for many fantastical stories, though most with the same tragic ending - the traveler all alone, in a familiar location but their loved ones dead or yet to be born.
