The world and story in “The Dawn of Annwn” does contain mature themes, BUT the manner of which the story is told and the campaign is played can make a run of DoA be from PG13 to R-rated.
Such themes include: corruption, gore, violence, fantasy violence, cannibalism, sexual themes, and language.
Many traumatic themes are purposefully avoided by the author but can be implemented by DMs for groups who prefer those extra horror themes be added

Religious lore and mythology used in Annwn is based on or inspired by Dungeons & Dragons/Pathfinder content, including but not excluded to: Asmodeus as the Lord of Hell; Hades (the place) & the River Styx being run by the Four Horsemen; and demons, daemons and devils being separate races.
These ideas do come from real world inspiration, but are not directly related to them or their origins in this fantasy setting.

“The Dawn of Annwn” does not intentionally push for nor against any religion or spirituality in the real world.

As of writing this answer, there is no exact date planned. Writing and playtesting will continue throughout 2024, and hopes of intricate art, accessories, figures and more are being workshopped.

Currently the only physical book available is “The Dawn of Annwn: Gluttony One-Shot Demo,” which is sold at Rosaleigh Arts booths at conventions (check the “Events” page for information or join the newsletter for upcoming sales,) or at a growing selection of NE Florida local shops, such as All Books and Comics/Jack’s Comics & More!
If there is a large enough request for physical books to be purchased and shipped online, we’ll definitely consider it! For now, however, only the above is true!
If you’d like to host selling Rosaleigh Arts and/or “The Dawn of Annwn” books at your store, head to the “Getting Involved” page for more information!

Word of mouth is one of the best ways to support! Sharing and talking about “The Dawn of Annwn” to your friends and local D&D groups is a great help! Sharing the website & trailer, joining the Rosaleigh Arts discord, and listening to the official playtests/playthroughs also help DoA’s growth!
And of course, buying and playing the demos helps us not only financially, but with feedback and reviews! Feedback is one of the most helpful things to make DoA be the best version of itself possible.
