Grain watched as the mana density around him rose significantly.
This meant Remus had died.
He had been inside of the tear for over an hour.
Grain knew he had no way of using Spatial mana inside, as he had planned for this exact situation. After experimenting with Chaos mana, Grain found a way to essential remove the mana manipulation from any being.
He had yet to try it on a living being, though the lack of Remus proved he had accomplished something. If Remus could still manipulate mana, he would have already returned, most likely instantly and without injury.
Grain decided to kill Remus immediately after killing Catherine and transforming John.
It was a fairly simple conclusion in his mind, Remus was also at fault for the sorry state these countries were in.
If he was going to rule, he would do it alone.
