Warcraft Battlefield

In 709 AD, the spacecraft driven by alien Kaitan (played by James Caviezel) crashed in Norway. His companions were seriously injured and died, the spacecraft was damaged and sank to the bottom of the lake. Kaitan mastered the knowledge of the earth and the local language by virtue of the advanced machines he carried with him. While wandering in the forest, he met the Viking Ulfric (Jack Huston) and returned to the village. Kaitan told the Vikings that he was looking for an "evil dragon", and this dragon was a monster on his spacecraft that escaped after the spacecraft crashed. The Vikings initially thought Kaitan was a liar, but as the villagers disappeared one by one, they discovered that the so-called "evil dragon" really existed...
