In 2375, the Son'a entered into a covert alliance with Starfleet Admiral Matthew Dougherty for the purpose of forcibly relocating the Ba'ku from their world and harvesting the metaphasic radiation in the planet's rings. When it was discovered by Jean-Luc Picard and the crew of the USS Enterprise-E that the Son'a were simply attempting to gain revenge on those that had exiled them, however, the alliance was dissolved and the Son'a were prevented from performing a procedure which would have annihilated the Ba'ku.
