Is the Dor being used up?

How exactly does the Dor being shoved into the Physical Realm function? Is it all of DnD's Investiture, or just most of it? When any of the Selish Arts (or other Arts being powered by the Dor) use the Dor, does it return to the masses of Dor that are stuck in the Selish Subastral, or do they return to the Spiritual Realm like Investiture normally does? Could the use of Selish Arts eventually return all of DnD's Investiture to the SR (even if it takes an extremely long time), or has it somehow been permanently grounded in the CR? Do AonDor Fabrials like the Light and Travel Plates continually return Investiture to the SR when active? Does Elantris itself (the massive Aon Rao) do that on a massive scale?

AFAIK this is a RAFO for Elantris 2. My best guess is that odium did more than pack the proverbial suitcase (stuff more into the CR than should fit) - he likely set it up so their investiture cycle returns to the CR instead of the SR. Total guess though.
