This achievement will require you to complete two main story quests.
Before the storm*** Spoiler - click to reveal ***Riverwood should be the first place you head to after completing Bronze Unbound. There is someone you should talk to there (Gerdur or Alvor) that will consequently send you to get help from the jarl. So head to Whiterun, convince the guard at the gates to let you inside the city walls, and tell Jarl Balgruuf in Dragonsreach about what you saw in Helgen.
Bleak Falls Barow*** Spoiler - click to reveal ***Lucan from Riverwood's shop will request you to find his golden claws. You will have to explore the nordic ruin Bleak Falls Barrow (located west of Riverwood). About halfway of the dungeon, you will meet Arvel The Swift trapped in spiderweb; kill him in order to get the golden claw he stole. Keep pushing forward and you will eventually come to a puzzle door, the solution of which is drawn on the palm of the golden claw (examine it in your inventory). Behind is a dragon shout word (Fus for Unrelenting Force) and the exit. Return the claw to Lucan and the Dragonstone to Farengar in Dragonsreach.
