Vikings will be quantifiably bloodier than ever in Season 4.

The History channel has announced that the period drama’s upcoming run will premiere Thursday, Feb. 18 at 10/9c — and run for a full 20 episodes, adding four hours to its original tally.

Ah, but there’s always a “catch”: Viewers will get 10 episodes in a row before there’s a break, with the second half to air sometime later in 2016. AKA a “split season.”

Per the cabler, Season 3 of Vikings culminated with the battle in Paris, where Ragnar seized victory from the jaws of defeat — but still returns to Kattegat dangerously ill. Thoughts of his death galvanize the forces who seek to succeed him as king, including his wife Queen Aslaug and his oldest son, Bjorn. Meanwhile, Lagertha continues power struggles with her calculating, former second in command, Kalf; Rollo betrays his Vikings heritage by remaining in Frankia; and Floki is seized for his brutal actions to the Christian priest Athelstan.

Joining the cast this season is Peter Franzén (The Gunman) as King Harold Finehair, a complex character who seeks to be King of Norway and a potential threat to Ragnar; Jasper Pääkkönen (Jet Trash) as Halfdan The Black, King Harold’s violent brother; and Dianne Doan (Descendants) as Yidu, a completely different character within the world of the Vikings who fascinates Ragnar.
