Helper's Letter

The forces of opposition gain strength by the day. Can't let my guard down for a second. It would be great to have a strong Assistant at a time like this. Someone approached me for the job, but I haven't met him before. He said he supports me and wants to help out, which I find pretty natural, but I'm still a little suspicious. He says he doesn't want anything in return, but nothing in life is free. I'd like you to investigate his identity. You will? Then here's what you should do. We use the rock at the Dead Cliff to exchange correspondence. Go there and bring the Letter of Helper to me.

Don't even think about reading the letter or giving it to someone else on your way back. Okay? Okay. Then go get the Letter of Helper from the rock at Dead cliff.

You found it? Let me see. Hmm, this is it. Thank you, but the important task still remains.
