I put together a Patreon page to support my D&D creative work and artistry. Everything I post there will be freely available to the public, with no paywall.
You're welcome to check it out: D&D Way at Patreon.
Here are just two of several research guides I'm working on:
• Dungeonsophy. A scholarly approach to the philosophies, worldviews, and mythic archetypes seen in the D&D Multiverse.
• The Official Paraverses of the D&D Multiverse. Untangling the discontinuities seen in Official D&D products. Each discontinuity is a distinct "paraverse" (parallel universe).
There are more projects listed at the Patreon site.
