11/12: I see the power of the Constellations has faded from you, but the potential to gain it again shines brightly as well. That, and the Celestial Spheres have returned so you can chart the stars all over again. For my final lesson, do just that. They can be the same stars as before or they can be different. While viewing the Star Chart, select a Minor Star next to the starting yellow one. Use a Celestial Sphere to upgrade it to obtain the power of a Constellation.

Upgrade a Minor Star Again

12/12: With that, I have nothing more to teach you. Now, go out in the world and collect more Astral Echoes. I will be needing them for... reasons. Once you've done that, I will reward you with a Grand Orrery of your own. While I don't have anything more to teach you, be sure to visit often, as I will have plenty more to sell to you. I'm proud of you, my pupil.
