Story:
Everything changed with the arrival of the Traveler. Long ago, it breathed new life into our system. Rain washed over Mars. Fresh air cleansed the skies over Venus. Soon after, humanity raced into the black, and colonized these newly remade worlds. It was a time of miracles — a great Golden Age.
It did not last. The Traveler had an ancient enemy. A powerful darkness that found us here on Earth, and nearly destroyed us. No one knows exactly what happened in those final moments, but we know this: we survived, and we owe our lives to the Traveler.
In our darkest days, Humans, Exos, and Awoken found the Traveler where it made its last stand, low above Earth, silent and immobile. We built the City — our last — within its protective veil, fighting countless wars to keep its peace. From that dark age, Guardians were born.
Now, a new era has begun, and the only hope for our future lies in unlocking the greatest mysteries of our past. You’re a Guardian of the last safe city on Earth, able to wield some of the Traveler’s incredible power. You are taking this mantle just as a new day dawns. Titans, Hunters, and Warlocks have finally returned to our long-lost worlds, only to find out we are not alone.
Defend the last safe City on Earth. Defeat our enemies. Explore the ancient ruins of our solar system. Discover all that we have lost. Become legend.
