The CW has released a new trailer for The 100 season 7, which is set to be the final season of the long-running sci-fi series. It was revealed last summer by the network that they were planning to end the show, which means that two of its longest-running shows, between this and Supernatural, are coming to an end. But not before we get one more one final round of adventures on future Earth.

The trailer kicks off with tensions rising as alliances form and allegiances are tested. The stakes are extremely high as the fate of the human race is at stake, with a war waging to determine how that future, if there is a future at all, is going to play out. Things become progressively large in scope, as a wormhole is discovered, sprawling visuals with little context are presented and battles rage on. There is also a particularly dramatic moment, in which, someone lights themselves on fire. It is an awful lot to take in for something that clocks in at just over two minutes, but it sets the stage for an epic final season.

Titled From the Ashes, the season 7 premiere centers on Clarke (Eliza Taylor) and her friends as they attempt to rebuild Sanctum, with a new threat rising in the woods. The cast also includes Bob Morley, Marie Avgeropuolos, Lindsey Morgan, Richard Harmon, Tasya Teles, Shannon Kook, JR Bourne, Shelby Flannery and Chuku Modu. Ed Fraiman directed the episode, working from a script by series creator Jason Rothenberg. Fraiman has helmed several episodes of the series throughout its run. Filming on the season was completed before the widespread production shutdown kicked in, so the show should get to finish out its run as planned. The final season will consist of 16 episodes.

In The 100 the human race has been away from Earth for 97 years, exiled in space. Now, a group returns to find a wildly transformed planet. But they soon discover that humans never truly left. Clarke was forced to lead a band of young delinquents who were labeled as disposable. They faced death at every turn. Their newfound sense of normalcy won't last long as their lives will be changed forever with threats both old and new set to push them past their limits and test their loyalties as they fight to save the human race.

Debuting in 2014, The 100 has been a staple of the network's programming lineup ever since. The show is loosely based on the novels of the same name by Kass Morgan. While the show was never a monster hit, it managed to maintain a loyal enough following to stay on the air this long. But it will leave behind a hole in the network's schedule that will need to be filled. The 100 season 7 premiere is set to debut on Wednesday, May 20 on The CW.
