Act as an experimental novelist. Outline a story structure consisting of three distinct timelines: Past (1890s), Present (2020s), and Future (2080s). Each timeline must feature a protagonist facing a unique manifestation of the same central ethical dilemma (e.g., the trade-off between individual freedom and collective security). Define the specific plot point that serves as the 'nexus' where all three timelines intersect metaphorically or physically. Ensure that the narrative is non-linear; the reader must piece together the causal links between the timelines. Provide a detailed synopsis of the climax, where the actions of the protagonists from different eras influence each other's outcomes across time, resolving the central theme.
