Book One of “The 100” is over, but Book Two is just beginning.

Season 6 of The CW’s post-apocalyptic drama premieres Tuesday night, and it’s bringing a new world and new characters with it. Maybe there are no good guys in the show, but there are plenty of interesting ones.

The last few minutes of the Season 5 finale set up the next phase of the series by jumping 125 years into the future, unveiling a new world in the distance, revealing Monty (Christopher Larkin) and Harper’s (Chelsey Reist) deaths and introducing fans to their adult son, Shannon Kook’s Jordan Green.

Those final moments only shared a few of the things fans will learn more about in the new episodes.

“Teen Wolf” alum JR Bourne is also joining the cast for Season 6 of “The 100.” He’s playing Russell, “a charismatic leader, a visionary and pioneer who will face the difficult moral choices emblematic of the hard-hitting show,” according to Entertainment Weekly. He’s the leader of a “peaceful society” who ends up having a “complicated relationship” with Clarke (Eliza Taylor).

Taylor told International Business Times at New York Comic Con last year that she wanted her character to have a new romantic relationship in the upcoming season, and it seems she might be getting just that.

It’s clear from the new characters, the new relationships and the four-minute Season 6 “The 100” trailer that many interesting storylines are on the horizon, but what can fans expect to see when the show first comes back?

“Still reeling after receiving Monty’s message, a small group goes down to explore the mysterious new planet,” the synopsis for Season 6, episode 1, titled “Sanctum,” reveals. “Back on the Mothership, several members of Wonkru face the consequences of their decisions.”

Stars Paige Turco (Dr. Abigail Griffin), Bob Morley (Bellamy), Marie Avgeropoulos (Octavia), Lindsey Morgan (Raven), Richard Harmon (John Murphy) and Tasya Teles (Echo) are all returning.

The Season 6 premiere of “The 100,” written by creator Jason Rothenberg and directed by Ed Fraiman, airs on The CW on Tuesday at 9 p.m. EDT.
