Updated the waiting list.
Was thinking of making the Sarkrith Spelleater next. But while the Sarkrith Thane got Pure Crafting, the Spelleater would get Realpolitik. Aka a nonmagic subsystem that allows them to bend others to their will, inspire allies, and other stuff politicians/generals do to make sure they remain in charge. Using Realpolitik makes you unable to cast spells/powers/similar for a period of time as the state of mind needed for it is anathema to the state of mind needed to channel mystic energies.
How does that sound?
