I've only just opened this, and I see that many are questioning the other writings as well. I'm certain that I can't explain it myself, but this doesn't seem like a hoax, so I will go along with it for now.

Well, my name is Sabrina. I am a knight in Reiarn, the capital of Jiranz. I don't believe I've seen many from there so far. It is a pleasure. I apologise for the curt introduction. I am about to oversee a training session and it seems that many of the attendees are late. You should take care to be punctual, should any of you desire to become a knight.
