Rules draw from Mörk Borg’s ultra‑lean engine: ability saves instead of attack rolls, swingy damage, and equipment that matters. Character creation is fast and classless; gear and risks define play more than builds.

## Theme and Setting

Tables, generators, and prompts speed up prep and make failure states interesting, not stalled. Vast Grimm leans hard into sci‑fi body horror: contamination, infestation, and desperate choices under pressure.

## How Play Feels
