Hearld of Manwë Súlimo, Maia of Eru Ilùvatar.

When Eärendil reached the shores of Aman, it was Eönwë who first greeted him and summoned him to come before the Powers of Arda.

When Manwë decided to heed the appeal, he gave his sword to Eönwë and sent him to Middle-earth to fight the War of Wrath, leading the Vanyar. It is said that it was Eönwë who overthrew Morgoth.

When Morgoth was defeated Eönwë played a key role in the aftermath. He took the two remaining Silmarils and held them for safekeeping, but when the two remaining Sons of Fëanor stole them and fled, Eönwë did not allow them to be slain.

Afterwards, Sauron paid obeisance to Eönwë and abjured all of his evil deeds. But because Eönwë had not the power to pardon Sauron, he commanded him to return to Aman to receive Manwë's judgement. Unwilling to receive humiliation and sentencing, when Eönwë left Sauron hid in Middle-earth and fell back into evil.

Second Age At the dawn of the Second Age, Eönwë came among the three faithful houses of the Edain and taught them many things; and they were blessed with wisdom and power and longer life-spans.

These Edain eventually became the High Men of Númenor.
