The previous season of "Vikings" showed a lot of deaths and pains. Lagertha (Katheryn Winnick) has been away, but she makes her triumphant return that may continue to be seen in "Vikings" Season 6. As the show is about to come to an end, fans may first see their favorite characters exploring a new world.

In an interview with Jack McEvoy, he told Express.co.uk "Vikings" Season 6 would explore entirely new worlds. As the show has done featuring other things like a time-jump, the new season might explore "different regions" of the world.

"I'm not entirely sure what will take place, but certainly excited to see it and find out where they do go from there," Jack McEvoy said. He also talked about his character as Helgi's sudden death and said he was proud to have a part in "Vikings."

Talking about a new world, one fan predicted Ivar the Boneless (Alex Høgh Andersen) went to Russia after the previous season finale. On the actor's Instagram, a Reddit user revealed he was wearing an outfit which believed to be during "Vikings" Season 6's production.

The user also questioned Marco Ilsø's appearance on the set, wearing the same dress Alex Høgh Andersen was donning. Could they be filming in Russia for "Vikings" Season 6?

Meanwhile, History dropped "Vikings" Season 6's first promo video, and it showed Lagertha's return. The second Queen of Kattegat screamed that "he" died for them - might be pertaining to her dead lover Heahmund (Jonathan Rhys Myers).

Bjorn (Alexander Ludwig) and Ivar the Boneless are also seen preparing for their final fight in Kattegat. Although the two have braved many battles together, their future in "Vikings" Season 6 remains in the air. 

In an interview with Variety, the show creator Michael Hirst revealed Ivar might be leading the charge in the upcoming battles in "Vikings" Season 6. Ivar is said to be a "little two-dimensional," and he has no secrets kept. He is also least interesting compared to Ragnar.

So in "Vikings" Season 6, fans are set to know more about Ivar. "We're going to see other aspects of his character and things we didn't expect from him," Hirst said.

Talking about the show's ending, Hirst explained he always knew where he wanted to take the show and where it would end. After he wrote the saga of Ragnar Lothbrok and his sons, he felt like "Vikings" Season 6 and 89 episodes are enough to tell their stories.
