hmm, i guess i can try to explain how Aether, kinda works if im not wrong. Well, first of all, nearly everything is made of aether, regardless its form or concentration.

there is the vital aether (wich is explained how it works in a lvl 50 main quest) with the cycle, with the void, with the aetherflow.

then there is also the magic itself. Some races (as far as we know, garleans can't) can draw the aether from its surroundings and channel it as an attack. It is also possible to use your OWN aether but its like, using your own soul (conjurer quests)


some people can even use massive amounts of aether/prayer to be vessels for primal summoning, when that person gets weak/the crystal aether ends. there are 2 options, you can either suspend it, or you can feed the primal being off your own aether, wich ends with the person phisical form disapearing afterwards. Leaving no phisical body behind.

not sure if it answers what you wanted but if you have more questions/ want to reformulate , say and ill try to answer!
