I guess the candles could have been extinguished either manually or through magic...

[ Hm, wait. ]

Actually, it would be helpful to know whether "shadow" here just means darkness, or if it's literally the shadows cast by objects in light. If it's the latter, maybe the darkness would have actually stopped her powers instead of strengthening them, since you can't cast a shadow without light.

Unless the light of the amulet on its own was enough...?
