Halfbreed

"Halfbreed" is a catch-all term for those with muddled heritage. Though some may use it as a derogatory term, most just use it as a throw away statement about the racial complexity of an individual's family tree.
For example, if someone's mother was a Human and father was a Rus, to which do they belong? Even more complex, if that same individual married an Orc, what would their children be? It's these individuals that are referred to as "Halfbreeds".
In former years, when race was a larger identifier, being a Halfbreed may have been more of an issue for people, but, once the Age of Exploration placed culture at the forefront of what defines groups of people, being a Halfbreed was simply a vestigial term.
