@Nevis I'm still very much interested in the Darknut if it's permissable, but if I have to do Sheikah, could I borrow heavily from Historia for the Sheikah lore and backstory?
"To the untrained eye, the average Sheikah may often be mistaken for a Hylian. This is partly due to the fact that they look exactly like the Hylians, save their notable red eyes. The origin of the Sheikah remain a closely guarded secret, though many believe they may be the last of the pure blooded ancient Hylians. The fact that Sheikah are religiously concerned with their bloodline and mating with other races is forbidden raises such beliefs. Other than this, virtually nothing is known of the Sheikah because they are a secretive people. From a young age they are indoctrinated into assassin training, and their bodies forced against their natural growth to instead allow maximum flexibility. Every Sheikah is a professional killer, and rightfully feared by all should one appear in public. Because of their secretive nature, the Sheikah don't have a large standing army, but rather prefer to kill enemy leaders before wars even start. Should the time come where war is the only option, the Sheikah can assemble their many assassins to murder an enemy army before they even have a chance to retaliate. Despite their unmatched skill at assassination, the Sheikah lack numbers and are prone to being killed off should they be surrounded by superior numbers. A Sheikah army would rather hide in the trees and fling needles at the throats of a marching army than show off in a bloody melee."
....alternatively. This could be an 'evil' Liz campaign where the oppressed races push back against the Hylian imperialism. Heck, with the Darknuts, you could have an Athalwulf and Alaric situation going on.
