Traces of Dikain

Everyone is content after defeating Amantorg and doesn't want to talk about it anymore, but it seemed to me that no one is wondering why those three had to be killed. Was it just on Amantorg's whim?
Pilborgs are savage, but they are not stupid. I know that very well, as I'm one of them!

I also know where the records of Amantorg are kept. Study his records and you might be able to find something.
He hid the <HFFFA7272>Chest<HFFFFFFFF> containing his records under a <HFFFA7272>Rock<HFFFFFFFF> on the <HFFFA7272>Sandy Road<HFFFFFFFF>. And he left the key of the chest with <HFFFA7272>Guide Forkroad<HFFFFFFFF> living in the <HFFFA7272>Area near the Wave Dune<HFFFFFFFF>. So go to Forkroad after you find the chest and you might be able to learn something.

It isn't good to see you idling like that when one of my own died such a pitiful death. Find the <HFFFA7272>Chest<HFFFFFFFF> hidden under a <HFFFA7272>Rock<HFFFFFFFF> on the <HFFFA7272>Sandy Road<HFFFFFFFF>. And bring it to <HFFFA7272>Guide Forkroad<HFFFFFFFF> in the <HFFFA7272>Area near the Wave Dune<HFFFFFFFF>.

Oh, I was about to go crazy from frustration and finally someone comes to see me. Poor Amantorg.
Sorry? Why did I not do anything? As a guide I must never leave this place. It is my job to stop any weak traveler from entering that desert of death.
Anyway, I'm relieved that you came. Please give me that chest.
