I would have expected you to be all over this.

Isn't life full of little surprises.

Here's a small mercy: it's the 14th of Neth - the eleventh month.

This calamity could hardly have been better timed for us - the harvest is in, yet the roads clear of snow.

The solution writes itself: simply construct shelters with walls thick enough to withstand the shadows, and evacuate the country within them.

If we pretend Korvosa's lands[1] form a grid 200 miles wide by 200 miles long, and we need a shelter at every ten-mile intersection if people are to reach them by sundown -

-

1. Contrary to an earlier tag that has since been corrected, Varisia doesn't need spatial shenanigans to fit everyone. I made an exceedingly silly error that I caught while writing Reebs's tag. ↩

Tile it in hexagons! it's more space-efficient - 

- we'd need four hundred such shelters -

on a grid the diagonal is half again the length -

which doesn't seem practicable to construct, let alone solve ingress, egress, and airflow for. 

What do you have against hexagons, Reeves?

What did hexagons ever do to you?

I was as a small child once stung by a bee. 

I swore a solemn oath never again to abide any shape or subject or matter that smacked to me of beeishness.

And my word is my bond.

...Really?

No.

While four hundred is doubtless an overestimate, as people are not evenly distributed, we have neither the spells nor diamond dust to create a dozen such structures, let alone dozens or hundreds. 

Reebs, you utter moron.

Four hundred is clearly an overestimate, because people aren't evenly distributed. Not that it matters, since we don't have the juice to build even twelve of these bunkers you're proposing.

...

...

Master Delmore, please.

Reebs is hell-damned, I'm acclimatizing him by stages.

Kindly cease.

Hm, what if instead of making people walk to a number of central locations, we boosted someone's movespeed way up and had them run around collecting everyone? Boost their carrying capacity way up too, or dump the people in Bags of Holding or Portable Holes?

A hippogriff can cover 18 miles in an hour, a Portable Hole fits fifteenish people, Bags of Holding typically less... no, this isn't going to work.

Too many people and too few hippogriffs.

Could we buy Portable Holes from Absalom, through the Pathfinder's Bag of Holding?

Not through that precise mechanism, no.

Also, if we need anything from Absalom we should hash that out soonish so no one has to make more than one trip.

And even with infinite extradimensional storage space or carrying capacity, there are just too many people and not enough hippogriffs. 

If we can't hide from the shadows, can we take the fight to them?
