I have been searching bacchus station for a solid week looking for anything related to the spider mystery as I dont necessarily feel that ft wallace is part of it (only really accessible in ch 6). But, that's my opinion.
Anywho, while I was scouring the area, I stumbled on this letter S, and not sure what the rock next to it is supposed to be, as it looks like a w, or bird symbols. Sorry the Pic isnt better, it really only shows the full S during certain weather times and this was the only shot I could get. Another rock above also resembled an O, but didnt get that in the shot.
I dont see anything that relates this to the spider mystery, but throwing this into the ether in case others want to check it out. I figure bacchus station has been a search point for it, so who knows.
Im currently still checking it out and the area to see what else I could be missing.
If this is an already solved mystery, lemme know so I can move on.
