I got this quest from the item, but I can't enter the Heart of the Forest to turn it in because I chose the Kyrians instead... And I don't think I'll change it any time soon.

I picked Venthyr as my covenant and I got this item from the Mystic Rainbowhorn. I got the quest from the item but I can't enter the covenant sanctum to turn it in. So the item may not drop exclusively to Night Fae players, but only they will be able to turn it in to complete the quest.
