Masteria Expansions, Names and the proof for each

Isaac...

have you read page 32 of Dran's Note?

We have a solid link now...

 Spoiler

Actually, yeah, I was just about to post about this. That line... It's not in the KMS book. It was added.

"I am even more disturbed by this Hidden Disciple, who wishes to combine terrible magic with advanced technology."

If we look at the facts:
Our primary antagonist in Masteria, at the moment, is a figure known as "The Alchemist".
Magatia is a town of Alchemy, based on the Black Magician.
The Black Magician, in GMS, has a disciple, who is not mentioned in KMS or any other versions.
Masteria's Alchemist resides in Krakia.
According to Foxwit, the residents of Krakia modify their bodies with advanced technology.


When you see all these things, it's pretty obvious that Masteria's Alchemist is the Black Magician's disciple mentioned there. How this is going to impact Masteria's storyline is unclear, Hopefully crimsonwood 2 will explain more.
