Finwë was wed to Míriel, and their son Fëanor was born. However, after the birth of Fëanor, Míriel languished and was unable to continue living. She went to Lórien to rest, and her spirit departed from her body and went to the Halls of Mandos. Finwë was grieved at the loss of his wife. Fëanor grew swiftly and was the most subtle in mind and skilled in hand of the Noldor. Fëanor devised letters that bear his name (Fëanorian letters), and was the first who discovered how to make gems. Fëanor was married to Nerdanel.
