I make zines and modules for a variety of TTRPGs, including other people's game systems and small one-off systems I've made on my own. I generally allow maps, stat blocks and other such content to be reused by other creators with attribution - I believe that sharing content like this makes all communities of small game designers stronger.
If you are interested in keeping up with what I'm doing, including blog posts hosted on my personal website and general updates on what I'm excited about in the TTRPG space, you can subscribe to my mailing list: https://buttondown.email/seedling
