Halloween Story
Part of the Rejuvenationverse
Set after the events of 'Luna Eclipsed

Imprisoned for a thousand years.
Banished from her own kingdom.
Now at last welcomed back by the Bearers of Harmony and her forgiving sister, Princess Luna returns.
But her mind is not what it once was.
History has been forgotten.
Legend has become myth.

But for three undying followers of the pony that once called herself Nightmare Moon, the legend and history is very real.
And the crimes of the past demand justice.
Luna has been forgiven
So why are they still so angry.
Why do they not recognise friend from foe.
What kind of Equestria created such ponies.

Faced with a foe unlike any other, the Mane 6, the Time Turner, an awkward librarian and the two sister Princesses of Equestria must face the consequences of a long-forgotten past uncovered.
The consequences of a thousand-year old civil war.
