Why? because it's the traditional ranking within the guild systems, plus novice at the "bottom rank"... for those studying but not yet formally taken as an apprentice.
No, I wanted 5.
So if those are historically accurate ones, then that is perfect.
I just came up with those on my own in the order I posted them, I knew Master and Grandmaster were the final ones, obviously.
It's good to know I got the other ones in order as well.
