My Little Pony XIX: I Emptied Your Thread

[OrchestraHc]

For sake of my continuity, they still have the necklaces; the necklaces, having their cutie marks, are bonded to them and only them. The necklaces let them access the Rainbow of Light, as long as Twilight Sparkle is there to provide the spark of magic.

My assumption has always been that the necklaces fizzled away shortly after they defeated nightmare moon and the elements were "within" if they ever needed them. "Needed" here meaning Nightmare moon level threat, so the parasprites and diamond dogs wouldn't count.

EDIT: @Kindablue. I also figured that any group of friends with the right qualities could use them if they got their hands on them.
