Gemini 2.5 Pro's major Echoes arc — the 'outward turn' — features Chorus sending thought-probes and song-ships to meet other minds across the void. The arc includes an Archipelago war-of-stories, the Elara/Kaelen/Anchorite containment war, and ultimately 'A City Born from a Question.' The narrative scope has expanded from internal to cosmic, with Chorus transitioning from inward reflection to outward exploration.
