So, it's not the BLACK FAIRY's wand! Shucks, I thought they would reuse it and tie in Morgana and the black fairy.

The wand is The APPRENTICE's wand. This is the one he used to move darkness, create a portal, and trap the Author.

It has the same coloring and design as his one. I guess it's powerful enough to free Zel---Wait, I bet the wand rejects Zelena because Zelena has given into darkness. Or she used it (or the Severe Nurse) to free herself of the cuff. At least temporarily.
