The strangely shaped ‘Silent Steele’ settlement looks akin to an island that had floated happily on an ocean for a time, until the liquid dried up, depositing the mass on an arid sea bed. Now, lights from buildings encircle the bulging middle of the rock. The precise origin of its name is unknown but has passed into common usage. More recently, an initiative to give the entire formation a form of propulsion has gained momentum. This would transform the settlement into a slow, land-based cruise of sorts, although the potential cost is thought by some to be prohibitive.
