This is the second terrain campaign from a very talented Eric Askue.  His first campaign introduced the world of Thorn (think Tyranids). Lots of cool terrain.
The Thorn World stuff starts out with some funky spires, that can be added to to form slightly larger pieces, and which can then be added to other bits (they nest together). Then there are OTHER bits that can nest with those, forming huge, eye-catching pieces.
This second campaign adds more to the world of Thorn, and introduces Scorch (desert terrain).
Certainly worth a look-see for those who play tabletop minis games and like printing their own terrain:

The all-in pledge is $55 USD (there are a few early bird slots left).  You can also add the first campaign files by adding-on an extra $55. USD
