Fin to Ravin: "Perhaps you should check that one out yourself, but from what I know....Its a very large structure....its roughtly a square, about 200 feet on a side, 50 feet tall, not including the central tower, which is 100...the outer walls are made of preserved ice about 5 feet thick, with several inches of strong metal underneath, and slope sharply outwards, so as to look like waves...It is about 30 feel from the shore, with docks out beyond that...on sand above rock, likely with lots of underground excavation..."
