Ysolda

Ysolda is a female Nord found in Whiterun, commonly near Dragonsreach or the market stalls.

Marriage
Ysolda is one of the NPC's which the player can marry using the Amulet of Mara. A marriage to Ysolda also gives the player a hundred coins to spend every day (this amount stacks if the player does not collect it daily) as well as the ability to trade with her. If you decide to live with her, she has a small house behind the Market District in Whiterun

Quest
Ysolda gives the player a quest involving delivering her a Mammoth's tusk, which she needs in order to give to a Khajiit caravaner. Doing so will increase Speech.
