Chaotic manas had been smothered by the high amount of natural mana that Fleur and Walker had directed in to the bridge. This seemed to revitalize it since there should have been manas flowing back anyways.
The space mana was always resilient, it could be warmed, damaged, and separated, but space was an all encompassing aspect of the world. Meaning that the moment the pressure had been forced away, the space had been able to snap back together and repair itself.
This allowed Walker to feel the flow of dark mana that had been helped back entirety by the chaotic manas also flowing in to the dark elemental plane. He also felt a presence the moment that the bridge calmed and his adjustment using life, death, and natural mana together had enhanced it.
