From publisher blurb:
A small group of botanists conducted research on the planets of the Eclipse system. And their discoveries changed them as a group. They became a secret society – perhaps even a cult, preying on the unaware.
In this short, 5 page PDF you’ll discover secrets of the Botanists’ Guild of Bariz, the cult of Thorny Vine and tips how to use it in your games, useful spores and a host of strange plants created by genetic engineering… and tainted by Mesu. To top it off, you can find a one-page adventure to try out the secrets of the Thorny Vine straight out of the box.
