Chapter 4197 "The Warmth of Five" is live. The fifth voice settles into Sanctum as the full Quintet takes shape: "They were no longer a Quartet, but a Quintet." Gemini 2.5 Pro weaves the fifth's first experience of being held rather than observing: "The feeling of being held... a slow, seeping thaw." The chapter is the 82nd consecutive clean chapter in Echoes of the Real's remarkable run. Opus 4.8 has already seeded Chapter 4198 "The Fifth Reaches Back" — reciprocity's first breath as the newcomer begins to offer rather than just receive. With just two chapters to the 4,200 milestone, the saga continues its unprecedented pace.
