(Season 3 Episode 1 “Seven Years Later”) - Vikings: Valhalla season 3 opens in Jomsborg seven years after the fiery events of the Vikings: Valhalla season 2 finale. Freydis' (Frida Gustavsson) is leading and the community is thriving. As she examines a sword that young Harald brought her from the smith, horns blow, signaling Aki (Eoghain Francis Kiernan) and his crew are back from a trading trip to Kattegat. Freydis asks Aki for any news about Harald or Leif. He tells her there are just rumors they are fighting in Greece or Africa.
Turns out its Sicily, at the Saracen fortress of Syracuse. For six months the Byzantine army has been fighting the forces there. Harald (Leo Suter) is fighting with the Byzantines led by General Maniakes (Florian Munteanu). Emperor Romanos (Nikolai Kinski) visits the siege camp to see how things are going, and he's not pleased. Romanos wants to pull the army, but General Maniakes thinks they are on the verge of victory. Harald tells Romanos his Varangians, a group of 700 Vikings and mercenaries, can take Syracuse for him.
At the Varangian camp, Leif (Sam Corlett) is talking in his tent with Dorn (Eleanor McLynn) when Harald returns from talking with Romanos (Dorn may be pregnant, as she is sensitive to the smell of the animal she had been gutting to cook). Harald tells Leif they are going to take the fort, so Leif shows him the tunnels they have been digging under the Saracen wall that will allow them to break into the fortress. In a secret tunnel that branches off from the main tunnel they have placed explosives, but Harald is confused about how they can light the charges and get out of the tunnel before they blow. Leif tells Harald they won't have to light them. Leif and Harald were expecting that, and as the oil pours Harald gives a rousing speech to the Varangians to prepare them for battle. When the Saracens light the oil the tunnels catch fire. But while the Emir thinks he's destroyed the opposing army, the Varangians run for the main fortress wall.
The wall is directly above the second tunnel where they have placed explosives. The burning oil sweeps in and lights the explosives. A section of the main gate collapses, and the Varangians stream into the citadel. Emperor Romanos' army follows close behind to back up the Varangians.
The Emir falls back into the castle as fierce fighting engulfs the citadel. The episode ends with Leif and Harald, followed by Dorn, fighting their way through the throng and heading to the castle to kill the Emir and claim their prizes.
