Some of you may have seen this excellent set of posts on the blog Generation Anthropocene, using details from George R.R. Martin’s novels to try and build a geological history of Westeros and Essos. It’s a fantabulous bit of geekery, marrying serious scientific know-how to one of the big challenges of writing speculative fiction, that task we refer to as “worldbuilding.”

I read those posts, grinned at the geekery — and then paused.

And clicked around a bit.

And sent an email.

A couple of months later, I am the proud owner of a tectonic map of Lady Trent’s world, along with extensive notes on the geology and climate of her planet. Mike Osborne and Miles Traer of Generation Anthropocene were kind enough to read through the first two Memoirs and take my description of the places that show up in #3, then help me work out the underpinnings of that world in greater detail than I had already. I’m pleased to say that my efforts on the climate front pretty much held up to their scrutiny; I don’t have any howling errors there. Figuring out the tectonics, though, gave me information I need for future maps, and provided a number of new considerations I’ll definitely be trying to work into the last two books.

I want to thank these guys publicly, because they have done yeoman work on my behalf. If this kind of nerdiness is your catnip, you should definitely check out the Generation Anthropocene site.
