I've been GMing a campaign of Heart: The City Beneath, except with a homebrew setting. I had my players work together to build a world for their backstories, and then I isekaied them into a twisted world of glass, wire, and bone. Their bodies have been transformed into what you see above.
Top to bottom:
Dial (D1-AL): Former android, now a Deep Apiarist
Shae: Former Elemental, now a Vermissian Knight (reskinned slightly as a Portal Knight)
Lalya: Former human, now a Deadwalker
Lou: Former avian, now a Heretic
Heart is a suuuuuper cool game for a horror setting and I encourage folks to check it out.
