Tall and beautiful, with the golden hair of her father Finarfin, she was called Altariel in Eldamar. This was translated as Galadriel, meaning "Lady of the Light", in Sindarin.
Galadriel was born in Valinor while the Two Trees were still alive. She and her brothers joined the Exile of the Noldor, coming across to Middle-earth across the northern ice. During the First Age of the Sun in Beleriand, Galadriel lived with her brother Finrod in Nargothrond, before entering the Sindar realm of Doriath where she was befriended by Melian and Thingol, her great-uncle. There, she met and married the Grey-elf, Celeborn.
From the beginning of the Second Age, the couple and their only child Celebrían, lived in Lindon; then in the eighth century they moved to Eregion, the realm of the Elven-smiths.
Later Galadriel and Celeborn crossed the Misty Mountains and came to rule over their own kingdom in the Golden Wood of Lothlórien. Commanding Nenya, one of the Three Elven Rings of Power, Galadriel used her power to weave a ring of enchantment and protection around Lothlorien.
During the time of the War of the Ring, Galadriel gave shelter and magical gifts to the Fellowship of the Ring. During the War itself, Galadriel repelled three attempts at invasion by orcs, and used her powers to bring down the walls of Dol Guldur and cleanse Mirkwood.
In year TA 3021, on September 29th, The Three Keepers of the Elven Rings departed from the Grey Havens to sail to the Undying Lands, Galadriel having been given permission by the Valar to return.
