Wade

Wade is the owner of Wade's Emporium in Denerim, and he is a skilled smith. Unfortunately, his perfectionism left him with very few customers, and to avoid having to eat gruel he has Herren taking care of business in his shop.

Origins
Wade can make, and give a quest for drake and dragon scale armors. When you visit Wade's Emporium with Drake Scales in your inventory, you will get the option to talk to Herren about the scales, which leads to Wade crafting Wade's Drakeskin Armor for you.

Awakening
Wade appears also in Dragon Age: Origins - Awakening, having moved to Vigil's Keep on account of Herren being paid by the monarchy to supply armor for the troops at Vigil's Keep. If the Warden-Commander speaks to Wade, he'll ask him/her to look for exotic building materials so he can "have a challenge once again" and make some excellent quality weaponry and armor. See A Master's Work for details. You can also mention the Drakescale Armor and purchase Wade's Drakeskin, Dragonskin, and Dragonbone armors from Herren, but the superior versions of each are not available.

Trivia

 * Writer David Gaider has confirmed Wade and Herren are a couple.
