So, a quick sort of overview of Wormgod's Harvest, another setting because I don't have the attention span to finish anything. The Wormgod shattered the world in the Age Before, and is sleeping in the dead core. The mites from its skin fill the air, turning it faintly yellow. They're afraid of living things, but eat dead things.
MagicShaping (a type of constructive biomancy) is a large part of Wormgod's Harvest, along with Miteworking, the other magic system. Houses are usually either grown with Shaping or built out of stone, and travel between the sky islands (yes I'm using that trope) requires Shaped creatures.
Miteworking is the equivalent to religious magic: by praying against the Wormgod, you can intimidate the Mites into doing things for you. Unlike Shaping, Miteworking doesn't require long, drawn-out rituals, but the Mites don't stay afraid of you for very long.
This is heavily inspired by Scrap Princess's Another Gristly Campaign Skeleton.
