History's Vikings have cleaned their wound, repaired their ships, and are ready to set sail once more. The season 4 premiere is coming in on the rising tide.

After a staggering time jump and months of waiting, fans will have the chance to return to Kattegat on Nov. 30. Ragnar (Travis Fimmel) the prodigal King is back and his homecoming will reverberate through the very core of his kingdom.

"In the midseason premiere, Ragnar's reappearance in Kattegat triggers a chain of events no one - except the Seer - could have ever imagined. He unexpectedly arrives home to see what has become of his sons and to handle unfinished business in Wessex with King Ecbert (Linus Roache)," History teased. "Meanwhile, Lagertha (Katheryn Winnick) plans a power play in Kattegat and Bjorn (Alexander Ludwig) prepares to fulfill his long-held dream to explore the Mediterranean in a sleek new boat built for him by Floki (Gustaf Skarsgård)."

As brutal as season 4A was, it was merely a setup for 4B.

"There's so many major events - major, major events - coming up," Skarsgård told IGN . "It kind of feels like the first half is a lead up to the second half that's going to happen in the fall."

For Bjorn and his brothers, their father's absence has allowed them a chance to explore their own desires. Ludwig's character is imbued with Ragnar's wanderlust, but he won't be the only Lothbrok intent on making it into the history books.

"I think you're going to see a big change in this season," Ludwig warned. "Everyone's kind of doing their best to make their mark."
