After Andrius saved her and her brother in that white void, he told her that he would make some insurance if something unexpected happened.
"Yes, but he's not like you. He is not dead and doesn't have Ayja's third eye like you. So I won't be able to make use of his body directly unless he's dead."

"Technically, letting him roam on the world after bringing him here is already Necromancy. But after he truly dies, I will be able to use him completely," Andrius said.
And that was what Andrius did. He went out of his way, breaking another natural law to make his way to the world. He made sure to watch them closely, picking up the best time when they were the most off guard.
He chose the moment when they thought they had won.
