His necklace say "Earth First", somebody scribbled that in the bathroom at Phoenix College.

"Earth First" is a radical enviro movment that started in New Mexico and Arizona. The current organization is not much like the original.

"Earth First" is also a motto. The emblem on Harmonies neckless is part of the uniform of members of the Green Army in my story. I guess I should post EarthSpirits ref sheet. It has the details and a good view of the unit patch. BTW, they are Gaiasts.
