You have uncovered a mangled journal. Parts of it remain legible, with a Williden Marshal claiming ownership over the contents therein. If the journal is accurate, then Williden may be found somewhere in the northern part of the Crater; according to the journal, he and his companions sought higher ground from the savage beasts of the Crater once their base camps were overrun.
Well look at this - my journal! I thought it was lost, much like almost everything else we brought into Un'Goro. I thank you kindly for returning this to me!
