These remains belong to an undocumented parallel branch of humanity—the Keepers—who diverged from our evolutionary path 800,000 years ago, choosing isolation and harmony with nature over dominance. As Russian authorities led by Colonel Sorokina attempt to weaponize this discovery, Ira and her former student Mikhail flee with a mysterious bone cylinder—the true Bone Atlas—containing the Keepers' accumulated knowledge and memories. The Keepers reveal themselves to be a dwindling ancient population with extraordinary abilities, including telepathic communication and enhanced physical adaptations. Ira learns she shares genetic heritage with them, explaining her unique ability to access their stored memories. At a gathering of the last remaining Keepers, Ira proposes selective disclosure of their knowledge to thoughtful human leaders rather than governments or militaries. This final convergence between the two branches of humanity offers a path to preserve their wisdom before extinction—knowledge that could help address the environmental and existential crises they predicted millennia ago.
