Setting sail for Ragol seven years after Pioneer I first established a colony on Ragol, Pioneer II arrives at Ragol and sets up communication with the Central Dome to prepare for landing. Aboard the ship carries the main wave of refugees of Coral. However, shortly after establishing connection with the Central Dome a large explosion rocks the surfaces of Ragol and all communication to the planet is lost.
