Write a fictional short story, in a third-person perspective, about an immortal protagonist who, after centuries of relative peace, must stop a group of rogue immortals from causing destruction to humanity. The story should include a clear description and explanation of the protagonist's immortality, as well as the origin and nature of the other immortals' powers. The protagonist should face significant challenges and conflict throughout the story, both physically and emotionally, as they attempt to prevent the other immortals from wreaking havoc on the world. The story must have a well-developed plot with a clear beginning, middle, and end, including a resolution of the conflict. Pay attention to character development, pacing, and intense action scenes to make the story engaging and easy to follow.
