Melkor hated the Sea, for he could not subdue it. It is said that in the making of Arda he endeavoured to draw Ossë to his allegiance, promising to him all the realm and power of Ulmo, if he would serve him. So it was that long ago there arose great tumults in the sea that wrought ruin to the lands. But Uinen, at the prayer of Aulë, restrained Ossë and brought him before Ulmo; and he was pardoned and returned to his allegiance, to which he has remained faithful. For the most part; for the delight in violence has never wholly departed from him, and at times he will rage in his wilfulness without any command from Ulmo his lord. Therefore those who dwell by the sea or go up in ships may love him, but they do not trust him.

When Thangorodrim was broken and Morgoth overthrown, Sauron put on his fair hue again and did obeisance to Eönwë the herald of Manwë, and abjured all his evil deeds. And some hold that this was not at first falsely done, but that Sauron in truth repented, if only out of fear, being dismayed by the fall of Morgoth and the great wrath of the Lords of the West. But it was not within the power of Eönwë to pardon those of his own order, and he commanded Sauron to return to Aman and there receive the judgement of Manwë. Then Sauron was ashamed, and he was unwilling to return in humiliation and to receive from the Valar a sentence, it might be, of long servitude in proof of his good faith; for under Morgoth his power had been great. Therefore when Eönwë departed he hid himself in Middle-earth; and he fell back into evil, for the bonds that Morgoth bad laid upon him were very strong.
