Hi everyone,

hope this is the right section. I have a technical question about realistic climatic possibilities: I draw a very long edge that divides the North's Lands from the rest of the Continent. North's Lands are always icy but the Edge works as a climatic borderline: onward the Edge, southwards, there is a big big marsh, like a sea that have got a few centimetres of depth; northwards, over the Edge, the perpetual ice.
Ice melts and runs down the Edge, fueling this marsh-sea for a kilometres and kilometres.

I would like know if it's a realistic scenario or not.


Thank you and sorry for my very poor English.
