The Calm Before The Storm!
Once the Snake Kingdom started the long-awaited war, they did so with their all, putting in all their efforts to make it as blown out as possible.
They came out with their all, mobilizing their strongest armies.
Like the Anemone Domain, the Snake Kingdom was also a mighty high-grade rural settlement with an even deeper foundation considering that they were the original overlords of this region.
Their depths were as deep as the abyss, their warriors were more powerful individually compared to the clownfish, they had the advantage of top power in the form of their hibernating snake elders, and they were known from antiquity to be the more cunning of the 2 species.
Perhaps, the only advantage where the clownfish were stronger than them was their mechs that had a lot of damage potential in large-scale wars.
Another fact was perhaps, their mysterious clown god.
