This page offers a guide on where to locate and how to complete Edmund’s Arrows, which is a Mystery located in East Anglia.
Loot the Arrows in the Throne
This Mystery is located within the large central building in Northwic. To begin it, loot the arrows that are covering the throne at the back of the building. When you take all of them, you’ll be approached by a woman asking about the arrows. Speak to her and she’ll offer to buy the arrows as she considers them relics. You may choose to sell them to her now, or you can keep them. If you choose to keep them, you can always return to sell them to her if you change your mind. To complete this quest, you will need to sell her the arrows, but in exchange for them, she will give you 90 Silver.
