Syfy's newest offering is "Defiance," a show set on post-apocalyptic Earth in the year 2046. The Votans, an alien species made up of six different races, arrived in 2013 looking for a new home in Earth.
The negotiations were ongoing for 10 years, until the Pale Wars began in 2023, not ending until the Defiant few put down their weapons in 2030 in the wake of the Arkfall event.
The Arkfall killed millions of Votans when the Ark fleet orbiting Earth exploded. The Votans blamed human, while humans blamed a Votan technology glitch. Either way, the explosion unleashed terraformer technology that drastically altered Earth's atmosphere and geology.
Now it is 2046 and Joshua Nolan, one of the Defiant few, is back in Defiance, where all the races reside relatively peacefully. But he'll have to work with Mayor Rosewater and the townspeople to protect the town from outside threats.
Here's a guide to the characters and various alien races.
