You study the stars, but move on from there to trying to hunt down metabiological organisms to study their viscera. You hear tales of strange energy being slying high above the clouds, and seek to bring them down to roll their bones. You become convinced language itself is an alien virus emergently conscious and aware enough to patrol and usually prevent its reference - and attempt to gut one of these word numen egregores on the altar of your own rational thought. Study, wait, and finally it hits you - you are the omen.
