Someone found files for an Amethyst Wizard and possible hint towards a "DLC 8"

User Kinzo from the official forums apparently found a text file showing a unit description for an Amethyst Wizard for the Empire since the Norsca patch: here

Interesting that along the file was labeled "dlc08". If this is true, it would complete the Empire's roster of all 8 core lores of magic. While it might confirm more stuff coming for game one, can it also mean something Empire-centric for content?
