If thats still not enough they can sacrifice their own life for a greater aether boost. That is still a limited amount, as we could see in the Akadaemia Anyder dungeons end, where a single life was enough to summon a questionably powerful primal-like being (Quezacotl).

Stopping a world end scenario, and restoring a whole planet required great sacrifices.
I wouldn’t be so sure about that, Emet made it quite clear he was tempered by Zodiark, so I would argue the continued cycle of sacrifices after his initial summoning were indeed the will of Zodiark.
