a moving pale garden

this would be more of an slowly creeping sense of pale terror to the game. the current pale garden biome is cool, but it could be so much more. imagine if the pale garden move, this would be a cloud or fog that slowly move through out your world. unlike other things like crops it move while you sleep, you get to see first hand how it creeks into your base, they trees turning grey and the grass seeming to die, to prevent this you could either toggle a game rule or make something from the pale garden into a protection from the garden. this could be made non-destructive by making all logs turned by the pale garden change back into what they were, also when you break a pale log it would stay a pale log.
