All the content here is a work of fan love, it is not official in anyway, but much effort, peer review, and test play work has been put into this content to make it fun, and balanced.
Special thanks to the discord-of-many-things, r/UnearthedArcana, r/Spelljammer communities which have helped shape this work.
