Why I got the feeling that this story will make harder to deal with Spike's death in Schemering Sintel?

WHY THE AUTOR IS A BAD-BAD-BAAAD-PONY.

Nope.
Nopenopenope.

Bad enough reading the b'awwfest of SS, but now we have to watch Spike turn into a monster? And what's the point? We KNOW what happens in the end?

Not downvoting, because I'm not petty enough top downvote a fic I haven't read, just... nope.

the black dragon is female..... unexpected. Either way, if it turns out she's Spikes mother, I won't be surprised, I though about that theory since Schemering Sintel

I suggest you add a chapter to smithering sintel notifying of this new story, otherwise some might not find this.

2695762 Half the text bubbles were cut off. Including Spike's final words.

2695326 So let me get this straight: Schemering Sintel ends with Spike dying before he is returned to his friends, Twilight losing her identity, and a resolution that doesn't involve the other five of the mane six?
