OK, I really got off on the wrong foot Thursday with Vindictus, the new MMO from Nexon that we'll see more of at E3. So, let's make a reintroduction with this trailer, giving the game's backstory. Vindictus, readers. Readers, Vindictus.
The broadest theme is familiar: Lone stranger in a strange land, here to save a despairing people. But I do detect some note of political manipulation and religious fervor (and I'm right; the wiki for Mabinogi, the South Korean MMO upon which this game is built, has a ton of spoilers). That probably sets up the moral relativism necessary for you to choose - and justify - your own path within the story.
