She is the daughter of Jarl Balgruuf's steward, Proventus Avenicci. She named her store, Warmaiden's, after her childhood nickname. Her father called her this due to her obsession with swords as a young girl. She is married to Ulfberth War-Bear. While she doesn't claim to be the best Blacksmith in Whiterun, she aspires to be as good as Eorlund Gray-Mane one day.
Through dialogue with Adrianne and Hrongar, it is revealed that she helps her father with his councilling for Jarl Balgruuf, and that she helps her father "in more ways than people realize."
Adrianne sells various enchanted and un-enchanted weapons and armor, along with standard smithing materials. She starts working early in the morning, and because of this, is available to trade from as early as around 6:00 AM. She will take a two-hour lunch break inside the shop at 12 PM before returning to work. Unlike most other blacksmiths, who keep working until their shops close around 8 PM, Adrianne will lay down her work around 6 PM and will head inside Warmaiden's. There, she spends the last two hours of each day selling her wares behind the counter with her husband before closing the shop at 8 PM.
Adrianne, like any blacksmith, offers a short tutorial of the Smithing skill. During this quest she gives the Dragonborn free materials to craft items, and the finished item can be kept afterwards. After this quest has been completed, it becomes unavailable with any other blacksmith.
If the Stormcloaks win the Battle for Whiterun, Adrianne mentions that the conditions of the city have not improved for her or her business. She also notes that if it weren't for her Nord husband, the Stormcloaks would have stopped purchasing from her altogether, due to her Imperial background.
Idolaf: "We'll pay whatever it takes. But we must have more swords for the Imperial soldiers."
Adrianne: "I just can't fill an order that size on my own. Why don't you swallow that stubborn pride of yours and ask Eorlund Gray-Mane for help?"
Idolaf: "Ha! I'd sooner bend my knee to Ulfric Stormcloak. Besides, Gray-Mane would never make steel for the Legion."
Adrianne: "Have it your way. I'll take the job, but don't expect a miracle."
- "Got some good pieces out here if you're looking to buy. More inside."
- "Don't forget to check inside the shop if you need anything."
- "Have you met my father? He's the steward, up at Dragonsreach."
- "I help my father in more ways than people realize."
- "You think all the counsel my father provides the Jarl is his alone? Hmph. Let's just say I advise the advisor, and leave it at that."
- "The finest weapons and armor"
- In the book "A Gentleman's Guide to Whiterun," she is stated to be a Nord, when she is in fact an Imperial.
- If the Dragonborn reaches Whiterun without having received instruction in the Smithing skill, Adrianne can guide them through the steps to fashion an iron dagger. Thereafter, the Dragonborn is welcome to make use of her smelter, forge, tanning rack, grindstone, and smithing table.
- If she dies, Ulfberth War-Bear reveals that there is no one to forge new weapons and armor, so he has to purchase it from the caravans. If she was on good terms with the Dragonborn, a courier will deliver 100 as inheritance.
- If the Dragonborn kills her, they will earn the disliking of Ulfberth War-Bear, and he will say "I should bash your face in after all you've done", although shopping at Warmaiden's is still possible.
- She is equipped with a steel mace and carries a key to the shop.
