A new Moon Mage metaspell is available for preview over in Platinum. It is a 1-slot Enlightened Geometry metaspell and its perquisite is Braun's Conjecture (and thus has a de-facto 40th circle req).

That said, I'll let them control the flow of information beyond the name for a few days and give a more detailed post when it moves to a Premium preview later this week.
