Do primals know that the aether they need to exist is not unlimited? Can a primal exist on its own if it drains the world? Do they know they would eventually run out of energy and cease to exist or is there and amount of aether that can make their manifestation permanent... or do they just ignore the implications of their aether consumption because it doesn't mesh with their goals? With no aether and nobody left to feed them belief do they just cease to exist?
