Closing the fracture was harder than it should have been. Normally, there would be a place where the energy of the fracture would build up, crystallizing and becoming a fracture core.
A person only needed to destroy the fracture core to have the fracture disappear, but since this fracture connected to the demon world, Zion and Nimreth had to forcefully close it from the outside, which was significantly harder, especially since Zion's knowledge of space magic was very limited.
"Are you even trying?" Nimreth asked, her voice strained
Zion shot her a bothered look. "The fuck does it look like? I know you see me straining to pull these two ends of space together! I don't even know how I'm able to grab space as it is! Fuck I hate arcane magic!"
"Stop complaining and use more power!" She shouted
'Stupid bitch!' Zion thought to himself as he increased his power output, straining his body as he helped close the fracture.
