Mars was a virtual representation of one of Arno Dorian's genetic memories, relived by a Helix initiate through the Helix Navigator.
Arno solved several riddles to find a part of the Nostradamus Disc.
In a peaceful field sewn with stones
A winged watcher waits.
Her gentle gaze graces all souls,
Follow to the resting place.
Notre Dame Cathedral looks over her daughters,
One snuggled between dame and Sainte-Chapelle.
There, the face of the Son
watches o'er his flock.
Beyond a Dauphine, the blue ribbons
Diverge, making a way for man and beast.
An assassin's victim struck a shrewd bargain
To acquire a city.
The treasure lies beneath the mount.
Arno retrieved one of the fragments of the Nostradamus Disc.
