This topic appears more interesting than two of the other topics in this subforum, while not being as hard as the other. Or at least, it will be more interesting when the number of participants in more than 2. So I will participate.
I will guess that
Justinian will be next.
Now the question is, am I just a random person who will never be seen here again after today, or will I check this again very soon, and should thus be guessed in return?
