When they completely lost the power to resist, the world would directly take away those remnants and "digest" them. As for what would happen after the "digestion" was complete, that was unknown to anyone.
It was possible that they would be transformed back into Origin, strengthening the power of the world. It was also possible that these remnants would be reassembled into large and small "planes" attached to the main body of the world; all of this was indeterminable.
Even Chaos might, because of these unexpected yields, give birth to deities that did not exist in their original fateful trajectories.
Laine and Erebus actually had only a short moment to explore these remnants; that was when the "world"-level power on the remnants was nearing erasure by Chaos, yet had not been completely erased.
