Set 97 years after a nuclear war has destroyed civilization, when a spaceship housing humanity's lone survivors sends 100 juvenile delinquents back to Earth in hopes of possibly re-populating the planet.
Clarke is yellow because she represents the sun, stars,
hope, and optimism. Lexa is red because she represents blood, war, and passion.
The blue on Clarke represents the sky because she is leader of the sky people.
The green on Lexa represents the ground because she is commander of the
tree/ground people. The blue is radiating from Clarke's heart because she makes
decisions with her heart. The green is radiating from Lexa's head because she
makes decisions with her head.
