Mechanic Feedback: Syzygy (Patreon)

~Yes, that's really a word.~

So "syzygy" (pronounced siz-i-jee), is when three celestial objects—such as a star, planet, and moon—are aligned. This gave me an idea for a mechanic I want to include in the Cosmic Dragon Breviary sort of along the lines of Hag Covens. Some special benefits the dragons get when three of them team up in a group.

Looking for thoughts on lore and mechanics here, as well as perhaps other benefits you think could be cool for this. Thanks, all!
