This is the base set for our Bizarchitecture terrain series, meant to represent the haunted, ever-shifting, living city of Cosmopolis from our tabletop RPG, Wayfarer: Things Beyond Wonder, though you could use it for any arcane/extra-planar ruins, This is in 15mm scale (our passion of the moment) but you can scale up by 120% for 18mm, or 180% for 28mm/Heroic scale gaming. The source models are available here in TinkerCAD, so if you want to hack them up/remix them, have at, but be sure and post remixes! I'll probably want to print whatever you make.
We've set up a Patreon page for anyone who's interested in helping to fund us so we can keep making free and open sourced games like Pocket-Tactics, Wayfarer Tactics. and others, not to mention the growing catalog of gaming miniatures that you can use for whatever you want! (Psst... we take requests and commissions...)
