Ok, so all three of the Memory Fluxes in Promyvion - Vahzl are used...

since that's where Tenzen, Ulmia, and Atarefaunet NO HE'S NOT LOUVERANCE are imprisoned.


ONE of the memory fluxes in each of Promyvion - Dem, Promyvion - Holla, and Promyvion - Mea are used for Shadows of the Departed.

What are the other ones for? Does it have something with determining which of the 3rd floors in each zone you will warp to? That's the only thing I can think of about them.
