I'm a longtime roleplayer and writer using World Anvil to build multiple worlds both for RP campaigns and various writing projects. I have two primary worlds I'm currently working on: The Morticene and Viridescence.   The Morticene (currently private) is a dark science fantasy setting taking place in a very distant post-apocalyptic future after biotech backfired on humanity, reshaping our species and our world.   Viridescence is a brand new collaborative setting that is just getting off the ground. In this solarpunk world, where advanced green technology has lifted the human race into a utopian state, it is the discovery of a unique magic that begins to regress society back into turmoil.   Feel free to reach out to me on discord (Innokha#8644) if you are seeking advice on an element of your world building involving biology/ecology/evolutionary biology/genetics, as those are my areas of specialty.
