Ares Prime

Ares Prime was the largest city on Mars, hosting multiple space-elevator stems coming down from Turian Flower communities in geosynchronous orbit above the planet. This was the center of the Aren empire, where the Empress of Mars lived, and where the emperor proposed the Deep-Space vessel Pegasus be brought down to the ground.

Backups of the TurTek Databanks were physically stored in a hidden location in Ares Prime, holding millions of duplication blueprints dating back centuries, including thousands of human beings quark-scanned down to the electron. They essentially held enough data to recreate an entire human civilization from scratch.
