Hyperborea was a place in greek mythology to the north (beyond the north wind) with various magical/mythical aspects (/patronise mode) - just watch the vid - It includes details of the mythology and how the myth has been utilised over time by various mystics/nationalists/racists, and latterly relating to the wafflings of Alexander dugin.
While there are some things I've heard dugin say about geopolitics that I can nod along with, I didn't realise just how mental some of what he says is - like a mix of Jordan Peterson and Julius evola (neither meant as compliment). Anyway, there's a few chunks of his writing near the end of the vid where he talks about the hyperboreans and why they mean northern people are inherently superior to southern people - not in a racist way you understand, but in some sort of magical/spiritual way, so that's alright then (like I said - similar to the spiritual racism shite that evola spouted). What a load of old racist bollocks.
(btw - I listen to this bloke for ancient history, not politics, so don't be surprised if he has any vanilla takes on Russia/ukraine - not relevant to the hyperboreans or the waffliness or not of dugin et al (at least on the history aspect)
