Var Smaugs skatt-hamstra en bugg eller ett in-universum? [duplicera]

Jag skulle vilja kommentera, men jag kan inte. Passagen i Silmarillion, som beskriver den första draken som skapar den första höljet av guld, är den här i "Of Túrin Turambar":

But Túrin passed away on the northward road, and Glaurung laughed once more, for he had accomplished the errand of his Master. Then he turned to his own pleasure, and sent forth his blast, and burned all about him. But all the Orcs that were busy in the sack he routed forth, and drove them away, and denied them their plunder even to the last thing of worth. The bridge then he broke down and cast into the foam of Narog; and being thus secure he gathered all the hoard and riches of Felagund and heaped them, and lay upon them in the innermost hall, and rested a while.

Ingen förklaring av något slag - verkar bara vara något de gör. Det enda som är värt att nämna är att Tolkiens drakar är väldigt slagna och stolta, så girighet skulle inte vara så konstigt i en sådan karaktär.

Också ingen förklaring till varför de skapades på detta sätt:

[...] But thereafter there was peace for many years, and no open assault from Angband, for Morgoth perceived now that the Orcs unaided were no match for the Noldor; and he sought in his heart for new counsel.

Again after a hundred years Glaurung, the first of the Urulóki, the fire-drakes of the North, issued from Angband's gates by night. He was yet young and scarce half-grown, for long and slow is the life of the dragons [...]

Så de kommer bara att bli till existens.
