From the MSQ and the intro to the Eden raid, we're left with the impression that The Empty is a giant white desert. As we go to fight the re-imagined by the WoL Primals, we clearly travel to other places which don't seem to be as corrupted or destroyed by the light as others. How did the Atlas Peak (Titan Arena) not turn to dust for example? Why did the Trench we fought Leviathan in still have some corals? (implying at least some sort of life)
