The Chronicles of Riddick

Five years after escaping the dark planet, Riddick has been in hiding, evading bounty hunters and mercenaries sent to capture him. After killing a crew led by mercenary Toombs and stealing his ship on planet U.V., he heads to New Mecca on the planet Helion Prime in the Helion System, after Toombs reveals his bounty originated there. Riddick is reunited with Imam, the man he rescued in the first movie. Imam believes Riddick is a Furyan, a member of a race of warriors long thought extinct, and wants to know about his homeworld and if anyone other than himself is left. Imam believes Helion Prime is the next planet to be conquered by a mysterious force crusading across the stars. Aereon, an Air Elemental, identifies the army as the Necromongers, religious fanatics who seek to convert all human life and kill those who refuse. The Necromongers attack and take control of the capital in a single night. In the battle, Imam is killed and Riddick escapes.
