If Skull's Crossing collapses? Spoilers and such.

[Jimmy "Big Daddy" Ho-Chunk]

This is all kinds of spoilery, so...

Spoiler:

My group is has just finished the Graul farm (all the Black Arrows died) and is headed back to town, so I'll likely start the next session with the flood. But given my players ability to really focus in on things, I can easily see them skipping the dam and going after the ogres. If that happens, then the dam is obviously gonna collapse, but if it does, can anyone suggest what happens to Magnimar?

Assuming Storval Deep averages 300' deep, 120 miles long, and 20 miles wide, then it contains 20,072,448,000,000 cubic feet of water that'll drain down river. Turtleback Ferry and Pendaka are clearly gone, and Bitter Hollow probably as well. Ilsurian will get flooded but Lake Syrantula has a lot of area too it, so Biston & Melfesh are probably okay. But that stuff will continue on down.

Does anyone think it's reasonable if Whistledown and Wartle get washed away?

What about Magnimar?

That much water is going to take weeks to flow through, but will it be fast enough to do more than flood Keystone, Beacon's Point, and Ordellia?

Has anyone had this happen and if so how did you run it?

Personally, I kinda like the idea of Magnimar being, if not destroyed, then seriously damaged which would give even more Chaos for Mokmurian to take advantage of with the attack on Sandpoint.

Thanks!

Spoiler:

The water will take some days to get there, so Magnimar might be able to mount some magical defence. It'll cost something epic and not be 100% successful, so the city will be heavily damaged and impoverished. Broadly speaking, the lower city will be flattened and the upper city completely unaffected.

They might be forced to appeal to the Academae in Korvosa, which will really smart. The loss of pride might hurt some of the nobles more than the physical devastation.

As it's been raining a lot all over the place, much of the river will be high anyway, which will make the flooding worse.

Amongst other places, the Shimmerglens will be flooded, so finding Myriana could be tricky. Also, when the dam goes down, Avaxial might escape. Quite what he does next is up to you. Black Magga might get washed downstream as well, and take up residence in a location of your choice.

I'd go for it. Don't pull your punches. But give them a chance to spot that something bad might happen, such as a local hunter warning about the dam, or a [mad] priest preaching doom and destruction. So when it does all go pear-shaped, they know whose fault it was.
