She was responsible of weaving the story of Arda. Vairë was counted among the Valier, the Queens of the Valar; though she was not as great in power or prestige as some. Her "storied webs" covered the Halls of Mandos, where she apparently lived.
With the passage of time and its many ages, her woven tapestries expanded and clothed all the walls of the Halls of the Dead.
After the death of Finwë, Míriel returned to life and dwelt thereafter in the house of Vairë. She was given the task to record the deeds of the House of Finwë.
