As far as I understand it is a 3 step process
1. Described by Clues
2.A different thing which might be connected to clues but I am not sure about(Could be connected to Mount probably telling you too much)
3. A simpler but not really simple cipher which is applied multiple times to each thingy
Unfortunately these are probably too obvious and I most likely am going to have most of this snipped, if not the entire thing
