Lighthouse, foggy areas, and hazardous water

A cool structure along side a possibly new weather/biome would be the lighthouse and fog. The lighthouse would be a tall tower found in a “hazardous water” biome which would be filled with large rocks and fog. Perhaps these rocks would be able to break boats as crashing into things used to do. The lighthouse would have a new block called the fog light, a very strong light-source that only works in fog, a new weather or some biomes may just naturally spawn with it. It would have a bit of other loot as well, and would probably be found on a small island. Maybe even at the top you could have a lighthouse Villegas or something
