Plenty – the breadbasket of the SKies – is less than a mile from the great Runoff Falls. Plenty's orbit matches the Falls, blessing it with constant rain and frequent harvests.
Most ships passing through the falls are crushed, swamped, or sent spinning out of control by the force of the water. Specially constructed grain barges, however, are able to travel through. These barges export food to other isles.
Less hardy ships planning to visit the Plenty must instead brave the Razor Passage, which is marginally less hazardous.
