MSQ SPOILERS!!! Question

I can see it being the Ala Mhigan resistance ideal of Rhalgr

Louisoix would have risked summoning primal versions of the 12 if he didn't stop the ritual, which he planned on doing.

The Archon’s plan was to summon the Twelve using forbidden arts known only to him. With their combined strength, he was certain that he could prevent the fall of the lesser moon. Such strength, however, posed a threat in itself. Should Eorzea’s patron deities assume physical form, it seemed more than likely that they would be prone to the same appetites as the gods of the beastmen. Should that prove the case, their mere presence would bleed the land of life. And so Louisoix would instead call upon a fraction of the Twelve’s power—enough to stay Dalamud’s descent, and no more.
“It seems a fine balance to strike. Are you certain you can do it?”
Louisoix’s voice was distant. “Mayhap not. But the Twelve cannot be suffered to set foot upon Eorzean soil.” And then, head bowed, he told her the rest.
