A new notice appears... this time it has been written on a piece of leather torn from somewhere. The writing is not very good.

A new note is posted. This time it is of a better quality. The note is written on a piece of leather with an eloquent handwriting. Greetings, my fellow puzzle-solvers! First and foremost I must once again thank you all for inviting me to crack this mystery in your ingenious company. I apologize that...

A new notice has been posted. Once again it has been written very hastily.

New ring found:

Last meeting was very fruitful. We ought to meet again as soon as possible.

Throat punch is bugged. Instead of doing stamina damage it deals regular damage in a bleed-like fashion, only much worse.

A new note is placed under the others. This one is written on a piece of paper torn from somewhere. It looks very hastily written.

Hey!

I found a similar ring. It says the following:
QSMYFUBGMSXQIMZM

Maybe we should meet up and see if there be any other similarities?
