Astrology For My Setting

In my setting the art of star gazing went from worship and stone circle used as calendars and observatories to in the Age ox exilon it became more natural philosophy as observations in hundreds of places were compared, refined and republished on stone tablets to map the universe and were portable. Some glass blowers hold a disc of special glasses and filters to see the heavens better but only the largest temples, kings or wizards would keep them. So these

9 Zodiac Constellations - gods and giants and dragons battled over these great celestial powers

10 Eyes from the void - gazing on creation, spying on minions and awaiting to herald the end times, some report when gazing on them they gaze back and curse spectator with the evil eye

11 Artificial stars - built by wizards and abandoned long ago, wizards still plot locations

Before Exilon the signs were local and tribal plants or animals or elements....
Slgns were more about clans or bloodlines and birth omens and who could marry 

I have this notion that elemental cults who claim element worship is superior to alignment have had a few ages they influenced...so might have some elemental oaths and gifts one day. Elementals believe their kind best and other elements at best serving the prime element. Then there were those all elements should be friends vs other planes.

In a much later age astrologers became less interested in mythology of old gods and more into wizardry and examination of mechanistic cosmic forces and magic fields. Also chariots and Hydras and centaurs and mermaids are pretty rare by this time
