I don't know how much of the old environment you're planning to include or how thoroughly the packs are going to be forced to move - if, indeed, some of them are going to need to move at all. (I'm a little fuzzy on all that. I know some lands are now completely uninhabitable, but...?) Regardless, I thought I'd put it out there that the Shadowclan had swampy, marshy territory like
this, and I'm pretty sure they weren't inclined to move (correct me if I'm wrong, Fen), though I'm sure they could adapt if they had to move. It would certainly be interesting to see them forced to move, but I still like the idea of marshes in the new world. (EDIT: I see in the main thread that most of Telk is, indeed, going poof; in which case forget about the boys keeping their territory, I look forward to seeing where they end up! A desert? A different swampland? The tundra? Exciting times. Just my opinion, of course. ^_^ )
Also, the Acropolis pack lived
at the edge of the earth, as it were, and it would be nice from an IC perspective if they could keep their territory - what with a certain other pack of displaced wolves on the move that would think their territory would make a lovely new home. But even if that wasn't possible, it would still be really cool to see some cliffs and waterfalls in the new world. They're gorgeous and dangerous and make for both very defensible territory and convenient hiding places for a lone wolf.
Let's see...on behalf of one of my wolves, it would also be nice to see some lush deciduous forests in addition to the pine so she could feel more at home, even though hers has been effectively razed to the ground.
Other than that, I definitely vote for the mountains, and agree that a Yellowstone-like place would be amazing.
Ooo! And maybe ruins. Like, I know native Americans are a thing in Telk, so maybe one of the centerpieces of the quadrants could be something like a long-abandoned
Mayan pyramid or
Machu Picchu on a mountaintop (yes, with llamas, lol) or the cliff-dwellers at
Mesa Verde. That, I would love to see. Imagine a pack making a place like that their home...or deciding the whole thing was cursed and doing their best to avoid it altogether. Oh, yes.
Anyway, there's my two cents. Take what you will. ^_^
