Yeah, this is another one of those grey areas in the lore. I can't say right now where I got this notion from...one of the cutscenes maybe. I do tend to look at "tan" notes as though the author is using religious metaphor.

If you had all sorts of alien life traversing past your "gateway world", you'd probably want some sort of police force (border patrol?) in place to ensure the safety of your world.

A dozen generations ago, kuliltu battled in the sea above

I interpret this to mean the Rusalki were in the upper atmosphere, standing watch over civilization as travelers passed through the Breach. After many years of this, there was an attack, or a "great battle", or a civil strife (Anonymous Quote (Note)).

and the High Priestess rung in the storm, leaving them to spill upon the plains.

After some great catastrophe (the battle mentioned above?), the Sudrans decided to "close their borders". The Rusalki, unable to survive in the Breach, had to move down below the planet's surface, but this is more or less a side-effect.

Should they ever be returned to the sea, I do not expect they will look favorably upon us.

The Rusalki did not like being stripped of their duties, nor being trapped on the planet's surface.

That's not to say this is the only interpretation of events. But it's the one I went with when I wrote the Story section.
