Secrets of Strugur
A distinction between sentient species with roots in Elven philosophy. Plenty of intelligent creatures can be found on Strugur, but only a few build stable civilizations; primarily Dwarves, Humans, Halflings, and most of all Elves.
To most the distinction is simply practical semantics for the rare occasions when one wants a word to describe something like “everyone I can trade with safely” or “forces the Kingdom might foster a dependable long-term alliance with.” To some Elves, though, it’s more about the natural order and even the intrinsic value of an individual. Needless to say, such Elves generally don’t make a good impression outside Viska among their “lessers.”
