Interesting. Though what does the Aedra have to do with it? Just asking, I don't understand much about the Aedra.
Nirn has ten satellites, the eight aedric planets, and the two moons. Bright objects in the sky can blot out the presence of less illuminated ones, or at least make them less obvious. The two moons are very bright and prominent. With them gone, many other celestial objects (such as the eight planets) would be easier to see, if only because you wouldn't have a big ass moon in your line of sight. (I mean honestly, Masser and Secunda are huge in the night sky. Their either very big or very close,)
As I labeled, it's only a fun thought, but when planets orbit planets, what's to stop those more distant satellites from influencing lycanthropes when Masser and Secunda are gone?
