I mean, the names alone are pretty hard to take seriously (not so much individually, but in total).
The funny thing is, the names were all, letter-for-letter, blatantly stolen from Norse mythology... From the Poetic Edda:
9. Then sought the gods | their assembly-seats,
The holy ones, | and council held,
To find who should raise | the race of dwarfs
Out of Brimir's blood | and the legs of Blain.
10. There was Motsognir | the mightiest made
Of all the dwarfs, | and Durin next;
Many a likeness | of men they made,
The dwarfs in the earth, | as Durin said.
11. Nyi and Nithi, | Northri and Suthri,
Austri and Vestri, | Althjof, Dvalin,
Nar and Nain, | Niping, Dain,
Bifur, Bofur, | Bombur, Nori,
An and Onar, | Ai, Mjothvitnir.
12. Vigg and Gandalf) | Vindalf, Thrain,
Thekk and Thorin, | Thror, Vit and Lit,
Nyr and Nyrath,-- | now have I told--
Regin and Rathsvith-- | the list aright.
13. Fili, Kili, | Fundin, Nali,
Heptifili, | Hannar, Sviur,
Frar, Hornbori, | Fræg and Loni,
Aurvang, Jari, | Eikinskjaldi.
14. The race of the dwarfs | in Dvalin's throng
Down to Lofar | the list must I tell;
The rocks they left, | and through wet lands
They sought a home | in the fields of sand.
15. There were Draupnir | and Dolgthrasir,
Hor, Haugspori, | Hlevang, Gloin,
Dori, Ori, | Duf, Andvari,
Skirfir, Virfir, | Skafith, Ai.
