Looking for Nightmare Moon story · 8:24pm Apr 1st, 2020
In this story a character (maybe a griffon, not sure) enters an area bordered by massive glaciers. There, he and his companions find a lost civilizaton, pony ghosts, and pony corpses with smiles carved into their faces and at the end (apparently) the arrival of Nightmare Moon. I just can't remember the title. Any help would be appreciated.
Respectfully,
