Is Rohan studying about rock humans? Since he's Rohan I don't think it'd be too far off that he knows about them from morioh. Also, pretty good Part so far, just wished that there was a singular and more direct translation so that we don't miss any types of quotes or phrases, I chose this because it had the most views/reads so I thought that's the most translations to read from, but that's just a nit pick.
