Cardolan, once the ruling kingdom in the area of the southern Barrow-downs, left behind many relics. The creatures of the southern Barrow-downs likely carry some of these relics if one looks for them.
'The relics of Cardolan can fetch a nifty price from the well-to-do in Bree-town. Since we are here, I thought I might offer you a little deal.
'If you collect these relics over the course of your travel, I will trade you materials that may be of great use to you.
'Is this acceptable?'
Any of the creatures in the southern Barrow-downs may carry trinkets and relics from the kingdom of Cardolan.
Edith Sweetrose will trade crafting materials for any relics of Cardolan you may find.
NOTE: Bounty quests are repeatable quests, but have a finite number of completions. This quest can be completed three times.
