Feel like that concrete slab you live on just doesn't quite do it for you? Maybe it's time to employ some workers, give them some shovels and turn it into some wonderful desolate ashland. At least that's what I would do if I was playing the Darklings in Terra Mystica. Not enough shovel in your life to just set out and start terraforming (regardless of what your neighbours might think)? Maybe a visit to your local cult headquarters is in order.
