Something I said elsewhere: the mermaid and merman swim through the aether.

That is why the fish is so revered.
This is an ancient art, lost to time, that the atlantus cthuthulu priestess was instructed in, by the shining ones.

they raised her through astral traveling, and through dreams. they created through her, a perfect portal, or in another language, a babylon, a gate for gods to emerge.

that is why many call her a mirror.
