The problem with dark magic is that it tends to take over whatever it's around. So, say you've got a forest with some dark magic in it. It'll twist and warp that forest into something hideous. And if you head into it, there's a good chance it'll warp you, too. But go in your must, as that's what you'll be doing in Forsaken Forest, a new game coming to Kickstarter soon. Check out the trailer.
