Why Did Every Pirate Want to Capture The Galleon

In 1628, every pirate network from Port Royal to Tortuga converged on a single Spanish galleon. The manifests listed standard treasure fleet cargo, 37 tons of silver and 4,200 emeralds, enough to make any crew rich but not enough to unite enemies. What that ship actually carried was a sealed artifact that had been moving across the Atlantic for over a century, part of a relay system older than recorded history. The chase stretched from Havana to the Florida coast, through hurricanes and Spanish naval ambushes. Pirate coalitions fractured into gunfights over the cargo. A Jesuit priest threw the crown into the Caribbean rather than let it reach Spain. Divers who recovered pieces from the wreck started speaking dead languages and drawing star charts they'd never studied. Because the artifact wasn't treasure, it was a mechanism counting down to an alignment 400 years in the future. Every containment attempt accelerated its growth. The organism it seeded now covers 923 square meters of seafloor, building an antenna that responds to signals 12,000 light-years away. The mechanism completes in 2057 during a four-hour celestial window that won't repeat for another 12,000 years. What responds when the transmission goes out is still unknown.
