From my perspective, this wiki serves to host official 5e content made by WOTC to keep it in one accessible location as well as homebrew content that falls under 3 categories.
1) Homebrew created by WOTC writers
- Keith Baker's Exploring Eberron
- Mike Mearls' ThinkDM
2) Homebrew that was meant to be official
- Legends of Runeterra: Tides of Bilgewater (From what I've gathered, it was meant to be a collaboration between WOTC or DND Beyond and Riot before it was removed for whatever reason. I'm unaware of other examples of such content.)
3) Homebrew with a wide-reaching cultural impact on the DND community
- This definition is much harder to define, but I primarily mean Critical Role given its prominence. Few if any DND products match its impact and remain unofficial.
I'm less inclined to include most Kickstarter projects like what you have presented. I've considered adding from projects I've backed or have interest in (Grim Hollow, Humblewood, honestly most projects by Ghostfire Gaming tbh), but I feel like they don't have as much of a place on this wiki as other types of homebrew we've hosted. I obviously don't speak for every moderator or visitor to our wiki (I know some who would prefer we didn't host homebrew at all despite our clear separation of homebrew content from official content), but that's at least my perspective on the matter. If Auroboros falls under either category and I am simply unaware, I'd be willing to add it to the page, but as it stands, I feel as if our effort is better spent elsewhere.
