All Rarity had to do was left things be. If she had just accepted the fact there was nothing between her and Spike, she would've still be alive. She would have been apart of the War, be a part of Twilight's coronation, seeing Spike become the Dragonlord...

Spike, spike spike spike spike spike spike spike spike spike spike

If Rarity would have just not poisoned the dragon, she wouldn't been eaten alive.

Becoming a disgrace of the Element she was supposed to represent, her hands stained by the blood of countless lives, her damned soul was sent to Tartarus where she suffered over and over again....

One moment however, the most unlikely visitor visits Rarity in her hell.

This was asked for several times, also a chance to sorta transition to the next and the final installment of the Spike/Rachel universe.

I'll do the cover art later
