Yes, it will take time. Modern astrologers get to be innovative, but maybe not accepted until many decades later. The story of how trans-Saturnian co-rulers relate to trad rulers is likewise emerging slowly.
If you have domicile, then you have other decisions to make: exaltation, fall, debility. Thoughts from this thread?
Is Chiron part of 12/12, David?
I was reluctant to include Chiron, or any asteroids. But, you've seen the testimonials, and I'm not going to discount them. Chiron's getting a lotta love from a lot of talented Mods, and even Hybrids.
12/12 is capable of including Chiron as a secondary Domicile-ruler, but the dignities and debilities are set by the Domicile-signs of the 12 major indicators in Direct-motion, which includes the Asc and the Age-indicator.
I'll try a thread explaining it, but it's rather involved, and we each have our own Rulership opinions. You might find it interesting though. I had to come up with some new terms, which aren't included in Trad. I do use it on a regular basis. Most of it is standard, but what isn't conventional tends towards radical, and requires explaining.
I'm adamant about the Ages, because I'm an expert on those, and no one else is being consistent about them. In fact, most tropical astrologers don't even know the astronomy behind them.
I'll put it this way: If you think you can just say that the Age of Aquarius has already begun, then you can move all the indicators wherever you want them to be, including Sun, Moon and planets.
