"When we cast the spell that cleansed the darkness, something changed within us. We fused again, but this time we can't separate. Now we are neither Ayu nor Tyll'a, but we have become something more. You may call our new form...Ayul'a."
((What exactly did they mean by "something more"? I don't know, but maybe the Creator does!))
“I can see that Ayul’a I need to find my other half I used to be a fused being but something happened and now we’re separated but recently I’ve heard him calling out to me in my dreams but I have no idea where he is will you help me find him”
Ayul'a nod. "He does. He hurt himself protecting us from the darkness, and in the process of helping him defeat it, we became trapped in this fused state. I don't think we'll ever be separate cats again."
