Vairë

Vairë the Weaver is the wife of Mandos, and is responsible for weaving the story of the World.

Vairë is counted among the Valier, the Queens of the Valar; though not as great in power or prestige as some. Her "storied webs" cover the Halls of Mandos, where she apparently lived.

With the passage of time and its many ages, her woven tapestries are expanding and will cloth all of the walls of the Halls of the Dead.

Etymology
In the Etymologies, the Sindarin equivalent of her name (Quenya "weaver") is given as Gwîr.
