The First Kindred of the Eldar to follow Oromë from Cuiviénen to the relative safety of Valinor. At first, the Vanyar dwelt in Tirion upon Túna in the Calacirya with the Noldor, but after the revolt of the Noldor they abandoned it, and moved for the most part to the slopes of Taniquetil, and their ruler, Ingwë, sits at the feet of Manwë.
Although sickened by the poisoning of the Two Trees and the theft of the Silmarils, the Vanyar did not join in the revolt and eventual exile of the Noldor. Thus J.R.R. Tolkien mentions them very rarely in The Silmarillion.
People who live contented lives are less likely to live in interesting times, and so J.R.R. Tolkien tells us very little about the Vanyar. The only other Vanya named in The Silmarillion is Indis, mother of Fingolfin and Finarfin as the the second wife of Finwë, king of the Noldor.
The only time the Vanyar participated in the events of Middle-Earth was at the end of the First Age after the voyage of Eärendil, as part of the Host of Valinor which crossed to Middle-Earth, rooted out the dungeons of Angband, and thrust Morgoth through the Door of Night.
