The Flame and the Jaws that Devour the World. Or what one of the Sept Terrion in Erebonia was meant to do.
To this day, few people know anything about what the two Sept Terrion of Erebonia actually were meant to do, let alone why there are two in Erebonia. Falcom is not in a rush to spoil their purpose, and so it falls to Kiseki Crack to try and guess what is being hidden!
Seven Divine Knights, multiple trials, Gnomes, Witches, the Great Power. We know what is there right now. But this is probably not what Aidios had in mind when she sent down the Sept Terrion. All we might have to go off of is the final (almost) boss of Cold Steel 1, and what it had to say.
So what else am I supposed to do except search for anything in Kiseki that might have relation to the flame and jaws?
Next is in the depths of search engines on the internet. And then, I found something that I’ve sat on for a long while and thought about.
Let’s go Biblical for a sec. The Book of Joel in particular, which is very heavy handed. The primary message is “repent and stop sinning, OR ELSE.”
What actually happens in the Book is that a vast horde of locusts come upon Judah, and devastate the land beyond recognition, an instrument of divine judgement upon people who are urged to repent and humble themselves before God. Because if they do not, then God is coming down and You Ain’t Seen Nothing Yet. It’s a time to “Beat your plowshares into swords, and your pruninghooks into spears”
…so, what does any of this have to do with what Loa Erebonius had to say?
It’s all in the wording of the Book actually.
Joel 2:3; A fire devoureth before them; and behind them a flame burneth: the land is as the garden of Eden before them, and behind them a desolate wilderness; yea, and nothing shall escape them.
This is how a vast swarm of locusts was described in the Old Testament, and in the old view they probably had jaws instead of mandibles. Metaphorically, they are the Flame and Jaws that Devour the World.
Remember the Black Records? The books speak of a battle that shook heaven and earth and broke the sky.
Joel 2:10; The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining.
Well! This is all very nice and all, but nobody said that Aidios was the kind of divinity that Old Testament YHWH was. In fact, she is most emphatically not if games like Sky 3rd have anything to say about it.
So now I have to find the final links between the Old Testament and the words spoken of the Great Power. And this is the something that I’ve been stuck on for a long long time.
What do we know about Zemuria before Aidios? What do we know about Zemuria before the Seven Treasures?
Not much – but we do know some things in particular. That there are, have been and still are many creeds and beliefs that originally were not about Aidios. Animism anyone?
Oh and that Gehenna has been around for… a long time.
This is what I believe. I believe that before Aidios, Zemuria was under the boot of devils and demons of Gehenna, as well as the wicked humans of their creed who oppressed the righteous. It was a time of strife and chaos.
And the Sept Terrion of Fire was one means by which the land was tamed and malignant influences were expelled from the land, as well as how overpopulations of monsters were purged. The judgement of Aidios was an unmerciful and harsh war over a long time, but one meant for a better future for those who deserved it.
And this is a path I believe led to the Treasure becoming more and more war like and violent, until it could no longer avert a clash against another Treasure over… well, I have some extremely vague guesses about how this came about, but I’ll have to keep them to myself for the moment.
Anyways the Sept Terrion of Fire became extremely belligerent and was broken into pieces as a result. Where the Aureole became over controlling, and where the Demiourgos fell into despair, the Treasure of Fire was consumed by (righteous) wrath.
But when the Treasure could no longer go on with its war, that does not mean that there are none in Erebonia who would not embody its spirit…
