Every world eventually meets the edge of its first architecture. The eclipse came when the ambition around the moths outgrew a single collection page and a single chain. We wanted markets, maps, permanent lamps, creator tools, stories, music, factions, and a living archive.
Moving forward could not mean abandoning the original swarm. The problem was not how to replace Sonic. The problem was how to expand without breaking the line of memory between the first flight and the next one.
That tension produced the central rule of the migration: the new sky must be additive. Original holders remain the reason the path exists. The eclipse hides the old light for a moment; it does not extinguish it.
