Season 3 of CW's popular superhero television series 'Legends of Tomorrow' began airing this past October, with the season finale premiering on April 9. But it looks the next season is already in the works, at least, that's what star Caity Lotz's recent tweets indicate.

Lotz, who plays Sara Lance/White Canary — a Star City vigilante and former League of Assassins member suffering from rage issues after a resurrection by the mystical Lazarus Pit — on the show sent out a tweet that consisted of a trio of behind-the-scenes photos with her other co-stars from the show's Waverider set.

Joining Lotz in the post captioned "SEASON 4 and still can’t take one good photo #legendsoftomorrow" are Nick Zano (Nate Heywood/Steel), Tala Ashe (Zari Tomaz), Dominic Purcell (Mick Rory/Heatwave), Matt Ryan (John Constantine), as well as showrunner Phil Klemmer.

The 18th and final episode of the past season saw the demon Mallus demand that the legends hand over the six totems, and saw Rip Hunter (Arthur Darvill) sacrifice himself to allow the team to make their escape. They eventually combine the power of the totems to defeat Mallus but have their well-deserved vacation interrupted when John Constantine arrives and reveals that Mallus was not the only demon released and that all kinds of magical creatures called 'Fugitives' are now a much bigger problem. 

A synopsis released by CW for season 4 followed up on the events after Constantine delivers the news, reading, "As the Time Bureau is distrustful of and ill-equipped to deal with magic, the Legends must team up with everyone’s favorite demonologist to set history back on track."

"Sara and Constantine are joined by compassionate inventor Ray Palmer, hotheaded ex-con Mick Rory, rebellious totem-bearer Zari, and heartbroken historian-turned-superhero Nate as they set out to save the world – and their legacy. It’s the familiar fun of the Legends time-travelling across historical events and encountering famous figures with an added shot of magical craziness!"

Klemmer had previously also given his own work-up of the main focus of the upcoming season. "[Season 3 Big Bad Mallus] is a sort of bellwether of bad guys to come in Season 4," he said. "Up until this point, we’ve been dealing with earthly and historical bad guys, and we certainly had fun with all of that, but this year we dabbled in the world of the occult, through Damien Darhk and his enterprises."

He continued, "But you know that Constantine is coming onto the show [as a regular] next season, so we want to go deeper, we want Mallus to be used as 'the tip of the iceberg.'" Klemmer continued. "He is not human, and we want to start playing with the idea that Earth hasn’t always belonged just to our kind."

Season 4 will see the show undergo quite a few changes. Keiynan Lonsdale (Wally West/Kid Flash is confirmed to be leaving after the season premiere, with another potential new team member coming in his place, and the likes of Constantine, Ava Sharpe (Jes Macallan), Nora Darhk (Courtney Ford) are expected to play larger roles.
