The Elder Scrolls V: Skyrim - Five Years Later

From the introduction: The year is 4E 206. It has been five years since the Dovahkiin destroyed Alduin the World-Eater. Though the Dragon attacks have become much less frequent, the war between the Empire and the Stormcloaks still continues; the Empire now weakened after the Emperor, Titus Mede II, was assassinated on his trip to Skyrim by the Dark Brotherhood.
