I'm not sure. It's more bizarre for me that this place has so many. Also the fact that this place lives on a flat of land, a rather large one at that. Surrounded by water, no less. Curious stuff.

[ The water bit being the more amazing thing. ]

Where I come from, we live on towers surrounded by the fogsea. Folks here call all that water the sea but for me, the sea is white-ish grey and you can fall through it, not swim in it.
