Little is known about her, except that during the Exile of the Noldor Irimë went to Middle-earth with Fingolfin, while the rest of her siblings remained in Valinor. Irimë's fate is unknown, she may have been slain or returned to Aman after the Dagor Bragollach, "Battle of Sudden Flame". She does not appear in the published Silmarillion.
Other Versions of the Legendarium
In earlier versions of the legendarium, Finwë and Indis had three daughters: Findis, Faniel and Finvain. It remains unclear if the third daughter survived in the final conception of Finwë's family tree.
