I was referring to “modern High Elves”, exclusively, but I can see how what I wrote could be misunderstood as a general reference to all Thalassians. I’ll rephrase:
The overwhelming majority of those individuals who would later come to form the impetus of the modern High Elves (i.e. pro-Alliance, anti-Horde) most likely weren’t living in Quel’thalas, and therefore wouldn’t have been under the jurisdiction of the monarchy.
