Since a little after Nightmare Night, an odd communications blackout has occurred with the Hearth's Warming Eve holiday world. With no ghoul of the Nightmare Realm brave enough to step forward into its overwhelming cuteness, the cause of this remained unknown. That was, until a single message was received by the Thank Luna realm, the only holiday between Nightmare Night and Hearth's Warming Eve:

"We are Harmony. Lower your defenses and prepare your holiday to be overtaken. All calendars will adapt to service us. You will be assimilated. Resistance is futile."

And then… nothing.

Now, the Nightmare Realm braces for an invasion… of adorableness. And only an alternate Mane Six, led by the Lich Queen Twilight Soulshard can stop them… by finding six, sacred artifacts: the Elements of Fear.

May god save her half-soul.
