Historical drama "Vikings" is set to air soon on the History channel and fans of the period drama have been waiting to know the story of Ragnar Lothbrok, the greatest Viking to ever live.

Season three will show the Vikings colonizing their promised land in Wessex, but viewers know this peaceful colonization won't last very long. In the first episode, Ragnar and Lagertha leave Kattegat to bring in settlers. But while they are away a mysterious wanderer named Harbard enters the land in the second episode. This wanderer is set to play a spiritual and mystical role, according to iDigital Times. Harbard is set to significantly influence Queen Aslaug, Helga and Siggy, as all three women dreamt of his arrival. However, from all the three women, Siggy will be most suspicious about the new wanderer, reports Design & Trend. What role with this wanderer play?

Ragnar and Lagertha are also interested in attacking and seizing Paris. This is touted to be the biggest battle yet in the Viking history and viewers should expect to see ample bloodshed during the battle. Also, viewers should continue to see a rift between Floki and Ragnar over religious issues, especially now that they are settled in England. George Blagden, who plays the role of Athelstan, told Zap2it that "There's definitely a rift being created between Floki and Ragnar due to Ragnar's religious curiosity." However, Ragnar always sees the bigger picture while Floki is concerned with religious issues.  Blagden confirms this by saying, "Ragnar is an opportunist, but he's a man of loyalty and integrity. The assault on Mercia is to make sure his people have a future and he's trying to find a way to negotiate with King Ecbert".

In the promotional video if the upcoming season, Bjorn, son of Ragnar, proposes to Porunn, a former slave girl now turned warrior. Will she say yes?

Season three of "Vikings" premieres on Thursday, Feb. 19 at 10 p.m. EST on the History channel.
