Entity: Adara
Adara is the embodiment of hope, is connected to the blue light of the Emotional Spectrum, and is bird-like in appearance. It is first shown during the Blackest Night event in Green Lantern vol. 4 #52 as Sinestro, recently transformed into a White Lantern, recounts the creation of the emotional entities. Adara was created from the first act of prayer from a sentient being caught in a fierce storm. Like the other emotional entities, Adara was attracted to Earth by the (White) Entity and its now being hunted by Krona. An artist error shows the Sinestro Corps symbol on Atrocitus' divining ritual map. However, since Parallax had already been captured, this was more than likely supposed to be Adara. According to Atrocitus' divining ritual, Adara can be found in the northeastern United States. Adara eventually chooses for its host a 14-year old girl from Livonia, Michigan, named Nicole Morrison. Nicole had been kidnapped and after being possessed by Adara, confronted her abductor and forgave him.
Later, Saint Walker brings Hal Jordan and Larfleeze to Nicole's location. Still possessed by the hope entity, Nicole appears to retain her sense of self, stating she is able to hear the hope in her parents' hearts as well as the crowd around them. Nicole goes on to say she can sense an emptiness in Larfleeze and tells him that his parents are still alive and they miss him. She also tells Jordan that he is afraid to hope and asks him why. Before Hal can answer, the group is interrupted by the arrival of Barry Allen.
After Flash and Jordan discuss Jordan's recent actions, the Indigo Tribe appears with Proselyte, who has chosen a host, and Black Hand, who appears to be brain-washed. Nicole confirms this, saying she senses no hope inside them. Tension grows about whose side the Indigo Tribe is really on. This is cut short when the mysterious figure appears again and releases Parallax, who possesses the Flash.
A battle then erupts between Jordan and the Parallax-possessed Flash. While this is happening, Nicole, Saint Walker, Larfleeze, and Shane Thompson try to defeat the figure. This fails when the figure rips Parallax, Proselyte, and Adara from their hosts.
Adara was later seen with Krona on Oa where it possessed one of the remaining six Guardians of the Universe. Adara was eventually free from Krona's control when the rogue Guardian was killed by Hal Jordan and is once again at large in the universe.
