THIS is a good story
Let me start off by saying this: Wow. This was a good story. Combining myth, legend, and religion all into one to make a beautiful masterpiece. Creative, creepy, and very well done.

I was quite intrigued by Cassandra. It was hard to imagine a child capable of such things...but the fact that she had an ancient soul...oh, that was good. And I loved how you managed to convey the fact that all the monsters and fears we've had as children were, well, real. But they weren't really hurting us, no. They were helping us. And compared to Cassandra, they weren't monsters at all!
The ending was quite satisfying too. Yes, there are many beasts in this world. I often say that, all monsters are human, but not all humans are monsters.
The writing flowed beautifully, and this just felt like a well-written, complete story. Excellent work! :)
