There were only three places in the Isles that were major apexes. Hogwarts, Avalon, and the Leyline Hub. Hogwarts was a given with the amount of mages that pass through here. Avalon had a lot as well, but considering it was currently inert, that was less likely. The Leyline Hub was the only place that had nothing special there. Well besides the portal network into the Feywilds. But no one knew that besides me, even though it's one of the most well known places in the world.
