In J. R. R. <entity_0>, the <entity_1>, also called the history of <entity_2>, began when the Ainur entered Arda, following the creation events in the Ainulindalë and long ages of labour throughout Eä, the fictional universe. The account in Valian years is generally not used when describing the events of <entity_3> and <entity_2>. Having crossed into <entity_2>, Fëanor was soon lost in an attack on Morgoth's Balrogs—but his sons survived and founded realms, as did the followers of his half-brother Fingolfin, who reached <entity_3> after Fëanor's death.
