The Masked Alpha finally left Odette at the tower.
Before he left, he made sure that the vines around the tower's wall were still working perfectly, so if Ymir tried to do something with his Odette, these vines would attack him instantly.
Most importantly, these vines were imbued by light elements back when the Masked Alpha still had holy magic. They would naturally signal a distress alert to him when they saw Odette getting hurt.
After making sure that everything was alright, the Masked Alpha had no more reason to stay, so he was forced to leave and search for his mate once more.
He passed through the barrier and entered the real world, where time passed on normally.
A thousand years ago, his kingdom was huge, covering almost the entire continent.
