It looks like fans of the hit TV series, "Vikings," are about to get served an even bloodier set of events when the show returns for the second half of its current season 4.

Spoiler reports hinted that gory battles won't be the only thing coming in the show as the recent developments now point out to the probable death of major characters.

During the San Diego Comic-Con 2016, History Channel rolled out the trailer for season 4B. The clip did serve its purpose of spilling some of the meatiest details on what to expect in the upcoming episodes.

In one of the scenes from the video, the Seer (John Kavanagh) told Bjorn (Alexander Ludwig) about an impending "calamity, chaos, tragedy, and death" that is heading toward Kattegat as its king, Ragnar (Travis Fimmel) makes his return.

Series creator Michael Hirst has earlier told The Hollywood Reporter about the same thing with regard to the fate of the Nordic kingdom.

Hirst, who also serves as executive producer of the show, revealed how Ragnar's comeback could usher in huge changes in the history of "Vikings." Could he mean the rise of Ragnar's sons who have now grown up to be adults?

When the first part of season 4 ended, it offered a glimpse of the Lothbrok brothers, all grown up to be strong and able to take on their father's dominion. But the most interesting of them all is Ivar the Boneless (Alex Hogh Andersen), who, despite his disability, is believed to be the greatest warrior to ever come out of Ragnar's household.

Andersen, a Danish actor, has been making the rounds in the social media sphere lately as he constantly offers updates to his fans on Instagram. In one of his snapshots, the young actor can be seen with a bloody face. In the aforementioned trailer, his character was found getting involved in the heat of the action, as compared to before when he would only be found tucked in safely back in Kattegat.

Although History Channel has yet to announce an exact premiere date for season 4B, "Vikings" is slated to return to the airwaves sometime this fall.
