Meet four new characters who are about to change life in the kingdom on Reign.

As the series prepares for its fourth season this fall, TV Line announced new people who will be making their way onto the show to embark upon some big changes. All of these characters will be men and might win the hearts of some of the ladies in the castle.

First, there's Gabriel, the son of Narcisse, who might have a thing for Princess Claude. Unfortunately, that may not go his way since the feelings might not be returned. Gabriel is described as a "sexy and highborn rogue who is also a plain-speaking realist."

Then there's Bothwell, a "warm-hearted bad boy" who is apparently in love with Mary. But is there a chance he might break her heart by killing someone close to her? According to history, that appears to be the case although it's not yet known if that will be a storyline in the series.

Another character is Lord Darnley who has a blood-claim to the throne in England. This man is similar to Francis in the sense that he has a "wildly ambitious mother whose love hinges entirely on his ability to secure a crown." And he might be more like Francis than expected since Darnley wants to wed Mary. If this happens, then they "could take down Elizabeth, giving [them] not just one nation, but two."

Viewers are also going to see a new face as Charles' brother Henry has been recast and will be older. He won't be happy to see his brother on the throne and he has a thing for women...and their jewels. There might be something likable about this new Henry though since he's also described as "sexy, clever and ambitious."

Reign airs on Mondays at 8 p.m. ET on The CW.
