Skyrim's main quest line consists of seventeen required quests and three optional quests. During these quests you discover your heritage as the Dovahkiin, learn why dragons have returned to the world, and find a way to respond to the dragon threat. Completing the main quest will take approximately 15-30 hours depending on your character's level. Eight achievements (170 points; 7 Bronze and 1 Gold) are directly tied to completing the quest line; in addition, several Dragon Shout-related achievements are inevitably unlocked during the quests. Quests belonging to main quest line are marked by dragon head symbol, which is shown above.
