That your warning the enemy is hier and attempting to distract is blatantly evident.
Yes, got carried away. Ant People are pacified and irrelevant to this.
So, Locusts. Sounds like insectoid interdimensional shapeshifters. Ravenous. Presumably led by Mantids.
I need a way to describe xeno alignment since species doesn't determine morality. I'll go with Cabal vs Pantheon to describe your competing Ascended factions. Those who eat children vs those who claim divinity: midnight vs twilight.
Locusts eat the masses, and then what? Meatsuits for the nephilim, right? That's the big payoff for the Cabal. Hybrids they can inhabit on Earth's surface, bringing all their wandering spirits out of the cold. Hybridizing with the remaining human bloodlines so they can enter Earth's afterlife. Bodies for the damned.
Ah, I guess the word you're looking for is nephilim.
This conflict is more ancient than human civilization's current iteration or perhaps humanity itself, so of course there are extensive rules limiting the clash of deities due to astral MAD. Hence the cryptic speech pattern.
