It’s a world-building, world-exploring book made to be shared and built upon. The book is Creative Commons licensed, which means that you can take anything from Symbiosis and use it in any way you want. Change it, use it in gaming, cosplay, novels, comics, and anything else you can come up with.
The art book will be published by Steven Sanders and you can click this link to get a beta version (shortened version) at a Pay-What-You-Want price. The book was financed by backers of his kickstarter campain and isn’t released yet. But the shortened version already contains 80 pages with a lot of Steven Sanders artwork.
