Something else I've been pondering. Is all this summoner lore just ascian propaganda to cause more strife via primals?
Bismark is alive and well in the first. He does not temper people, he does not run amok trying to fight everything that flies, he isn't after more and more aether, and judging by the greenery growing on him, he isn't sucking the land dry by simply existing.
Primals as we know them on the source do. All of the primals were summoned by ascian means as all the beast tribes learned from them supposedly and we have no idea how long bqck this started. The waring triad is by far the current oldest known case.
They call Bismark a fae i stead of primal, but maybe they don't have a word for them. We haven't heard of any other primal like being on the first before eden showed up nor has there been any mention of summoners.
So i am lead to believe most of the summoner lore about aether, demis, egi, and everything else is flawed. its build off a.meams of summoning that exists solely to imbalance the aether for calamities.
