Both EWalker and Midnight were in the air moving at a rapid pace. They knew where the endless night forest was and they also knew that going back to Genesis would be pointless since they would both be moving toward the forest anyways.
It was also clear that there was a large group of elves making a move to enhance their borders since this forest mixed with their natural territory as well.
This wasn't just a precaution against an unknown group, but also a simple fact that they knew Akma, Gil, and their own queen would not be able to venture in to this area to help or fight. Alma and Gil were both occupied with the spirit tree and were not even told about this event. Simply to ensure their focus and lack of stress.
