13 parts Complete As peace returns to the world, Shadow, Silver, and Amy find themselves facing new challenges-ones that test not only their strength but also their very resolve. With the destruction of the Eclipse Cannon and the defeat of Sienna Robotnik, they believe that the worst is behind them. But, an ancient and powerful force stirs in the shadows, threatening to unravel everything they've fought for.
When the heroes are confronted with an unexpected force from beyond their understanding, they are forced to question their pasts, their alliances, and what it truly means to protect the future. Their strength will be tested as never before, and new and familiar faces alike will emerge-some to aid them, and others with their own hidden motives.
In the face of this new darkness, Shadow and his allies must come to terms with their greatest fears and face a battle that will challenge everything they know. The line between light and dark begins to blur, and no one can be certain who, or what, will stand at the end of the war. With the world's future at stake, the question remains: Can they overcome the darkness within themselves before it consumes them all?
