Complete story — includes the ending
The Disciples eliminate Sheidheda's guards and severely wound the Dark Commander. As the search for the Flame commences, a Red Sun eclipse begins and Emori lowers Sanctum's shield so that the affected bugs will attack, killing Knight as he tries to break into the reactor; the toxin causes Gabriel to hallucinate Josephine Lightbourne who urges Gabriel to fix the Flame and use it to save humanity. Nikki attempts to take revenge on Raven, but ultimately decides to leave Raven to live with what she has done. Indra and Sheidheda work together to escape; having learned the truth about her mother's defection to Sheidheda's side, Indra decides to leave the Dark Commander to die of his wounds rather than outright killing him. Gabriel begins using Eligius technology to repair the Flame, but changes his mind and destroys it forever instead. Taking control of the situation, Clarke kills Doucette and forces Cadogan to open the anomaly to their friends and travel through with Raven, Jackson, Madi, Emori, Indra and Murphy, but Sheidheda directs Bellamy to Madi's sketchbook containing proof that she has the Commanders' memories. With Bellamy refusing to stand down, Clarke reluctantly kills her best friend and retreats through the anomaly, but is forced to leave Madi's sketchbook behind.
