The main quest is relatively boilerplate, and none of the sidequests boasts anything remotely resembling a compelling story. If there is one massive flaw in Dragon’s Dogma, it’s that nothing in the game is particularly appealing on a purely narrative level. If the story sounds fairly boilerplate, it is. That means you are the chosen one who can enlist the aid of beings known as “Pawns,” stop the dragon and of course stop the end of the world.
In Dragon’s Dogma: Dark Arisen (the “Dark Arisen” refers to included DLC of an island with monsters you can access not long after the start of the game but given their high-level should probably not try and fight till the post-game), you are “The Arisen.” An especially nasty dragon attacked your village and took a personal interest in you and ripped your heart out.
