Though I was initially shocked and saddened to see the lowest rating I've ever gotten, I'm happy there is more than surface-level critiques to it.  You raise a fair point of Cassandra seemingly becoming less interesting, but I've always veiwed and written her as an all-powerful 'mary sue'.

I also understand that once a creator has made something and allowed others to experience it, they cannot (and more importantly should not) tell people how they should feel/view their work.  How you interpet my stories isn't something I should influence outside of said story, I should rely on my literary techniques of the story to do that... however, if you'll indulge me, I would like to state my intentions with this entry into Cassandra's tale.

Simply put, she's losing more and more of her humanity the longer she uses her powers.  She'd grown used to killing people by the second story, which was something she did her best to avoid in the first story, and now considers herself separate from humanity.  The morals she tried to hold onto at first, like insisting on Morgan acting like her mother, not a worshipper, she's letting go of slowly.  She can still empathize with people a bit, like Sebastian worrying about his relationship with his sister reminding her of her love for her brother, but she had also gotten to know him a bit by then too.  Basically, it's becoming harder for her to naturally act 'human' and more does as she wants when she has the power to.  In a sense she has regressed menatly to be more childish.

Since I only plan on releasing chapters for Cassandra on Halloween, I know I can't just say "Wait until next year to see how I build from this", each story shouldn't have to rely on a new entry to validate it, and for failing to acheive that I apologize.  I will try to grow from this and do better, thank you for bringing this to my attention.
