Miriam tried fighting her mentor but she risked everything on ultimate power just to defeat him. Every shard of power she accepted within herself with every demonic creature slain...and she discarded none of them even when others like Johannes told her to. Now that she defeated her mentor...she felt just as evil as him. Her kindness was fading from her soul. In the end, her mentor Gebel was right...she was just like him.

You see her laughing and feeling a bit ominous and ask her: "Miriam? Are you alright?" "Never been better. I get it now. I get why this power was destined for me. Now Im gonna make humanity suffer." she said with a malicious grin.
