Lady Mantillon (also known as "The Dowager") is a member of the Orlesian Council of Heralds who can be found at the Winter Palace in Halamshiral during the ball held for Empress Celene's peace talks.
Involvement
During Wicked Eyes and Wicked Hearts, she can be heard speaking with another noble. Each time you pass her you will hear her talking about one of her late husbands.
Her first husband, Lauran, died during the war between Ferelden and Orlais.
Her second husband, Phillipe, was thrown off of his horse.
Her third husband, Pierre, died from rosallia. After his death, she swore off marriage forever.
The story of her fourth husband is told in two parts. [first part:] She was married to a man named Maximillian, who "swept [her] off of her feet." Their marriage was apparently seen as a scandal, as he was almost half her age. [second part:] She was horrified to learn of Maximillian's death; he was killed by a bear, and it took four chevaliers to hunt down the animal that killed him.
Her fifth husband, Gerard, died under much more questionable circumstances. He apparently "fell" from the Grand Cathedral's bell tower. "To this day, no one knows why he was there."
Her sixth husband, Hervé, was apparently an acquaintance of the man she is telling these stories to. The couple had installed a rose garden, and Hervé was stung by a bee. Unfortunately, it turned out that he was allergic.
The Dowager had told her seventh husband, Renard, never to drink aquae lucidius on an empty stomach. He died after being poisoned by three glasses. She takes comfort in knowing that "at least he died at Chateau Haine."
Her eighth husband, Nazairer, died when he was "tragically crushed by a cartload of fine handbags."
Her ninth and final husband, Atienne, died in a "violent tailoring accident."
Once the Dowager has finished her story [she must be passed by ten times], the Inquisitor can ask her if she would like to dance. The Dowager will marvel over the Inquisitor's impressive understanding of The Game, since they are a foreigner. However, she turns them down, saying, "you have other dances to perform first. Perhaps you will save me a dance for later."
After completing Wicked Eyes and Wicked Hearts and returning to the war table, the operation Dance with the Dowager: The Allemande will be available.
