Skyrim Quest: Bleak Falls Barrow
Bleak Falls Barrow is the third quest in the main storyline in the game The Elder Scrolls V: Skyrim
This quest is unlocked after completing the quest Before the Storm
Follow the Jarl to Farengar's lab in Dragonsreach
Farengar is working on some project related to dragons. He wants you to find a Dragonstone, an ancient stone tablet with a map to dragon burial sites, from the ruins in Bleak Falls Barrow. The Dragonstone holds the clues as to why dragons are returning to Tamriel.
At this point, you should follow the walkthrough as listed in The Golden Claw Quest
It is possible you already have the Dragonstone if you had already done that quest, so you can immediately give it to him to complete the quest. If you do not have the Dragonstone, travel to Bleak Falls Barrow to recover it.
