The Riverwood Trader is a small general-goods store located in Riverwood, run by the siblings Camilla and Lucan Valerius. Recently, the shop was broken into, and the thieves stole Lucan's prized Golden Claw.
Lucan will give the player a quest (The Golden Claw) in which he wants you to retrieve the claw from Bleak Falls Barrow and bring it back to him in exchange for the coin from his latest shipment.
After investing 500 gold (SpeechPerk) in his shop, Lucan will have a total sum of 10,000 gold or more. After his funds are depleted, you can either wait for 48 hours to get him restocked, or if you save your game then kill Lucan Valerius and then reload to the save before he was killed all his money and stock will be restored (works with all merchants). This is a much easier way to get rid of huge amounts of items than running around to every Store or Theives GuildFences.
If Lucan is killed, his sister Camilla will take over the store.
If both Lucan and Camilla are killed, no one will run the store.
After completing The Golden Claw you can marry either Lucan or Cammila (only if you wear the Amulet of Mara).
Upstairs books "Song of the Return Vol 2", "Song of the Return Vol 19", "Song of the Return Vol 7" and "Song of the Return Vol 56" can be found. However, taking them will be considered stealing,unless you marry Camilla.
