@martin I had a go at realistic caving in a module. The PCs fight only twelve goblins, but they know the terrain, and the PCs don't.The terrain has a metro-style map to show an overview and Bayeaux Tapestry imagery for contents. None of the images attempt realism. https://gitlab.com/bindrpg/aif/-/jobs/artifacts/master/raw/The_Goblin_Hole.pdf?job=build@ng76
