>How does azyr even work exactly
the short answer is: gw didn't think about it, so you shouldn't think about it either

the long answer is: the realms are as much physical places that move in the void and that you can see with the naked eye like one would see planets in the sky as they are weird magical condensates that look like physical places but that otherwise defy time and space and what used to be the laws of reality, azyr might appear as large as as the cosmos itself despite being as big as any other realm, plus back in the old world azyr was connected with clairvoyance through the reading of the stars because the magical wind would distort the path of light coming from distant constellations and making them appear in a different position in the sky of the old world, so if you had a telescope and knew where the constellations are actually supposed to be you can observe where they appear to be at a given moment, calculate the distortion of the wind of azyr and thus its fluxes and movements and thus get magic insights about all kinds of stuff, so it's very much possible that azyr is a normal realm, but that its constellations appear as the night sky for everyone due to the distorting effect of azyr magic

the short version of the long answer is: pic related
