This appearance of selfish faineance in the Valar in the mythology as told is (though I have not explained it or commented on it) I think only an 'appearance', and one which we are apt to accept as the truth, since we are all in some degree affected by the shadow and lies of their Enemy, the Calumniator. It has to be remembered that the 'mythology' is represented as being two stages removed from a true record: it is based first upon Elvish records and lore about the Valar and their own dealings with them; and these have reached us (fragmentarily) only through relics of Numenorean (human) traditions, derived from the Eldar, in the earlier parts, though for later times supplemented by anthropocentric histories and tales. These, it is true, came down through the 'Faithful' and their descendants in Middle-earth, but could not altogether escape the darkening of the picture due to the hostility of the rebellious Numenoreans to the Valar.
Even so, and on the grounds of the stories as received, it is possible to view the matter otherwise. The closing of Valinor against the rebel Noldor (who left it voluntarily and after warning) was in itself just. But, if we dare to attempt to enter the mind of the Elder King, assigning motives and finding faults, there are things to remember before we deliver a judgement. Manwe was the spirit of greatest wisdom and prudence in Arda. He is represented as having had the greatest knowledge of the Music, as a whole, possessed by any one finite mind; and he alone of all persons or minds in that time is represented as having the power of direct recourse to and communication with Eru. He must have grasped with great clarity what even we may perceive dimly: that it was the essential mode of the process of 'history' in Arda that evil should constantly arise, and that out of it new good should constantly come. One especial aspect of this is the strange way in which the evils of the Marrer, or his inheritors, are turned into weapons against evil. If we consider the situation after the escape of Morgoth and the re-establishment of his abode in Middle-earth, we shall see that the heroic Noldor were the best possible weapon with which to keep Morgoth at bay, virtually besieged, and at any rate fully occupied, on the northern fringe of Middle-earth, without provoking him to a frenzy of nihilistic destruction. And in the meanwhile, Men, or the best elements in Mankind, shaking off his shadow, came into contact with a people who had actually seen and experienced the Blessed Realm.
In their association with the warring Eldar Men were raised to their fullest achievable stature, and by the two marriages the transference to them, or infusion into Mankind, of the noblest Elf-strain was accomplished, in readiness for the still distant, but inevitably approaching, days when the Elves would 'fade'.
The last intervention with physical force by the Valar, ending in the breaking of Thangorodrim, may then be viewed as not in fact reluctant or even unduly delayed, but timed with precision. The intervention came before the annihilation of the Eldar and the Edain. Morgoth though locally triumphant had neglected most of Middle-earth during the war; and by it he had in fact been weakened: in power and prestige (he had lost and failed to recover one of the Silmarils), and above all in mind. He had become absorbed in 'kingship', and though a tyrant of ogre-size and monstrous power, this was a vast fall even from his former wickedness of hate, and his terrible nihilism. He had fallen to like being a tyrant-king with conquered slaves, and vast obedient armies.

如果诺多没回中土那就没有小埃兰啦~不过迈雅+精+人类的血脉融合依然有。不过，盖章了noblest和fairest的精灵是露西安，不是某些自认高贵的阿门洲“海归”。我不确定她算不算“半精灵”，后来所说的“半精灵”都是immortal+mortal的结合，她是immortal+immortal（divine），她大概算“半迈雅”（这啥？）。所以，庭葛当初来不了维林诺啊，否则露西安去哪里找贝伦？人类去哪里找fullest achievable stature？
