Palaven

Palaven is the home planet of the Turians. It was razed by the Reapers despite the fact that the Turians were one of the only races in the Galaxy to actually possess anti-Reaper weaponry. No-one knows what state Palaven would be in now if it had not been razed since it was home to one of the most technologically advaced races in the Galaxy at the time, but now it has been reduced back to a prehistoric state as the ecosystems of the planet needed to reboot. Meanwhile, the Turians either live offworld or in giant metallic cities dotted around the planet.
