Alexander's Hetaroi

Francis Walsingham "the Spymaster" for Elizabeth. They really need to justify her inclusion since she'd be the third leader for England.Also, while I'm not holding my breath about this, do hope they'll give one of these Leaders a Unique Governor in the vein of Suleiman's Ibrahim. That was a fun concept that I wish they had expanded upon more in NFP.
I'd love for one of his promotions to just do an "inquisition" in one of your cities.
She'd also be great for expansion and culture, but Victoria and Eleanor already took those abilities so this would make her different.
