Eönwë the Clumsy

[Gwaihir the Windlord]

The opening of Of the Rings of Power and the Third Age:

'When Thangorodrim was broken and Morgoth overthrown, Sauron put on his fair hue again and did obesiance to Eonwe, herald of the Valar, and abjured all his evil deeds. And some hold that this was not at first falsely done... but as it was not within the power of Eonwe to pardon those of his own order, and he commanded Sauron to return to Aman and there recieve the judement of Manwe. Then Sauron was ashamed, and he was unwilling to return in humiliation and to recieve from the Valar a sentence, it might be, of long esrvitude in proof of his good faith; for under Morgoth his power had been great. Therefore when Eonwe departed he hid himself in Middle-Earth, and he fell back into evil, for the bonds that Morgoth had laid upon him were very strong.

He fled after Eonwe's decree, of course, ran away and hid out until Eonwe was gone.
