What are your favorite unofficial settings of D&D that you wish would WotC would publish?
(Note: Your personal homebrew world not included.) These aren't old settings that have been published in full form before but not yet in 5e (e.g., Spelljammer, Dark Sun, Planescape). I am talking about unofficial settings that may be the personal homebrew settings of WotC/TSR staff (e.g., like Monte Cook's Ptolus) and/or settings that have limited publication but which never got full publication as a fully-realized setting with a sourcebook (e.g., snippets of Iomandra in Dragon Magazine).
For me:
- James Wyatt's Aquela
- Chris Perkins's Iomandra
Aquela and Iomandra are both settings focused on more oceanic worlds with sailing, archipelagos, and island-hopping adventure. A good island-hopping setting would be absolutely fantastic, IMHO, for D&D, and both of these setting scratch that itch for me. Iomandra, in particular, is a fantastic spin on the 4e base setting. With its
heavy focus on dragons, it would also be a great setting to draw out the First World echoes and draconic themes of the latest
Fizban's Treasury of Dragons book.
