Cuiviénen was said to have been on the shore of a large gulf in the inland Sea of Helcar in the far east of Middle-earth. It was an eastern bay of the Inland Sea of Helcar, formed by the meltwaters of the pillar of Illuin.
After the First Age and the War of Wrath, the Sea of Helcar (and Cuiviénen with it) was drained, leaving behind only the Sea of Núrnen and the Sea of Rhûn, prompting the Elvish adage "and to Cuiviénen there is no returning"; both a reference to physical geography and a metaphor for the Sundering.
In YT 1050, the Awakening of the Elves took place. The Elves dwelt here for a long time in bliss under the starlight and were content. Here the Elves were divided into their three basic groups: the Minyar (Vanyar), Tatyar (Ñoldor), and Nelyar (Teleri), here they learned and developed the basic skills of survival, culture, and language.
Unfortunately, Melkor discovered this land first before the other Valar. Many Elves feared him and they were forced to hide, and those unfortunate enough to be left behind or overwhelmed by fear and unhappiness were taken or slain. Then, years later, Oromë discovered Cuiviénen on his travels throughout Middle-earth. Oromë reported his discovery back to the Valar in Valinor and after some debate they decided that the Elves would be safer living in The Undying Lands, in the peace and protection of the Valar. Oromë returned to Cuiviénen and there spoke with the Elves regarding their removal to Valinor. The first Sundering of the Elves then took place when the Eldar, the name that was given by Oromë to the Elves using their own tongue, departed from Cuiviénen to Valinor. Some of these Elves refused to leave through fear of the unknown, turned back after reaching the huge range of the Misty Mountains, or simply decided to stay in Middle-earth through choice.
It is unknown how long the remaining Avari remained at Cuiviénen during the First Age, but they were there when Men awoke at the first rising of the Sun in the nearby land of Hildórien, and its Elven residents befriended early Men and apparently taught them the basic skills of survival.
