Nightmares are creatures that inhabit the hearts of the Brokenhearted. Whereas some people can be cured from a broken heart simply by restoring the piece of heart that was missing, those that have Nightmares dwelling within them will be a harder challenge, with Oliver needing to defeat them before the person is cured.
Each Nightmare is indicative of the virtue that has been stolen or lost, often indicated in the name of the Nightmare itself.
Due to them being beings of the Dark Element, all Nightmares we weak to the Light element.
