In the Outskirts there is in some people an ability called shaping. Shaping is the power to rearrange reality, although it has its limits.
However, evil has spread across the Outskirts. The corrupt high shaper, Stafford, has exiled the grand shapers, with the exception of the Zeropolite Abram Trench; the other four were forced to go into hiding. The high king has extended his control to all of the outskirts except a few hidden locations.
