Vikings Season 3 News: The Lothbroks greatest threat is Power

The Vikings will be raiding our homes once again when it comes back on air this February 19 via the History channel. With the new promo video circling around, the Lothbroks will return for a 10-episode series that will dwell on the threat laid against them: Power.

 The latest Vikings trailer kicks off with Ragnar (Travis Fimmel) and his son Bjorn (Alexander Ludwig) atop a snowy mountain. "Why do you want to fight?" the newest king of Denmark asks his eldest child. "What are you fighting for? What do you see?"

The young warrior then answered, "The power of a King."

In the last season, King Horik was afraid that Ragnar will take away his crown, so the king devised a plan to kill Ragnar and his sons. But he failed because Floki, a supposed ally of Horik, turned against him at the last minute.

At the end, Horik was killed by Ragnar and became the new King of Denmark. With the death of Horik, Ragnar is flooded with powers in his hands but a lesson that he has bestowed to his son in the season 3 teaser video was - authority comes with consequences.

"The power is always dangerous," he warns Bjorn. "It attracts the worst and corrupts the best." Ragnar then reveals to his son that he never asked for the power he's received. "Power is only given to those who are prepared to lower themselves to pick it up," he states.

Vikings Season 3 airs its premiere on Thursday, Feb. 19, at 10 p.m. EST.
