Investigate the Taken anomaly on Io
The Drifter nods and leans to one side as he sees you. "I've been hearing my Gambit regulars talkin' about some wild energy spikes over on Io. The Taken are real aggressive in that region. Seems to me like there's something out there they're tryin'a protect." He shakes his head and smiles at you with lightless eyes. "I'm sure you'll get answers once you go out there and mow some of 'em down." He catches a coin you didn't see him flip. "Get out there and see what you can find. I'll make it worth your while."
