I had a short story collection in the early 1980s which contained a story called 'Them' by Rob Heinlein. I have since found that story elsewhere but there were other stories. One about a man who insults an elf (I think) and he gets punished by not being able to touch water. There was also another one about a man who was sent to a parallel dimension ruled by Yero and everyone is immortal but could also be badly wounded, it was a kind of hell
Any ideas as I would love to read those again
