Именно так: "Melkor 'incarnated' himself (as Morgoth) permanently. He did this so as to control the hroa, the 'flesh' or physical matter of Arda. He attempted to identify himself with it. A vaster and more perilous, procedure, though of similar sort to the operations of Sauron with the Rings. Thus, outside the Blessed Realm, all 'matter' was likely to have a 'Melkor ingredient', and those who had bodies, nourished by the hroa of Arda, had as it were a tendency, small or great, towards Melkor: they were none of them wholly free of him in their incarnate form, and their bodies had an effect upon their spirits...Sauron's, relatively smaller, power was concentrated; Morgoth's vast power was disseminated. The whole of 'Middle-earth' was Morgoth's Ring, though temporarily his attention was mainly upon the North-west"
И сейчас эта мощь всё ещё осталась: "The dark spirit of Melkor's 'remainder' might be expected, therefore, eventually and after long ages to increase again, even (as some held) to draw back into itself some of its formerly dissipated power. It would do this (even if Sauron could not) because of its relative greatness. It did not repent, or turn finally away from its obsession, but retained still relics of wisdom, so that it could still seek its object indirectly, and not merely blindly. It would rest, seek to heal itself, distract itself by other thoughts and desires and devices — but all simply to recover enough strength to return to the attack on the Valar, and to its old obsession. As it grew again it would become, as it were, a dark shadow, breeding on the confines of Arda, and yearning towards it." (HoME vol. X, Myths Transformed, текст VII).

Да, насчёт золота, каюсь, не знал ("дабы дурость видна была"). Похоже, читал "по диагонали" и проглядел. Ну ничего, сейчас у меня 10-й том уже в "бумажном" виде появился:-).

А насчёт Колец жаль, не получилось...
