It's a Friday night, and the Muay Thai fighter from Phoenix is about to make his professional debut at the Hard Rock Hotel and Casino in Las Vegas. He peers into the lighted mirror, turning his head left, then right, before a fight official appears at his locker-room door and announces that he's up next.
Chasteen and his team walk silently down a hallway of The Joint, the Hard Rock's event center. Guttural screams spill out from fighters as their limbs strike the air and spar pads (whap, whap, whap, whap) during warm-ups in the backstage locker rooms that line the hall.
The fighter steps into the elevator with his corner men -- Chasteen's younger brother, Damien Earley, a professional kickboxer who also trains in Muay Thai, and seasoned trainer Bob Karmel.
Nick's barefoot and wearing a mongkon, the sacred headpiece that Muay Thai fighters don like a crown. Despite his garb and gloved hands, he doesn't look as though he's about to enter a ring and endure elbow jabs, shin kicks, and merciless knee blows before a crowd of more than 2,000 bloodthirsty fans.
A scorching, 120-degree breeze stirs dust in the streets before passing through the windowless ruins of former mansions on the flanks of Camelback Mountain.
The largest ghost town in history extends to every horizon of the Valley of the Sun -- now a superheated no man's land of crumbling walls, dead trees, and dry, debris-filled pits that used to be swimming pools. Only a few settlements remain, mostly to provide services for people passing through.
The date is January 1, 2114.
