The Warg and Warg Rider Appreciation Thread

[SamwiseGamgee]

It is trully delightful to share such epic stories of wargs and their varied natures with one who so clearly shares my views and opinions.
Wargs are a strange enigma. Neither wholly good nor wholly evil. They are perhaps the exception to many rules. Few know why wargs obey anyone, with their razor sharp wit and brain powers. One suggestion is that it is not a true warg who serves the orcs. I disagree. even the mightiest of beings (and wargs are counted among them) can be warped by evil. Take Saruman, for example.
So, a warg is perhaps rather like Tom Bombadil-neither clearly good or clearly evil.
Who knows? It could just as easily been a warg who had aided the hobbits in their quest, perhaps a far off descendant of the wargs of Rohan? Perhaps Tom Bombadil was even a warg? It is a puzzling perplexion which I feel could be a fine debate. Before that, though, I'd like to hear more of the origins of the wargs of Rohan. How did they come to be there? Whom did they serve? Were they gifts from Eru or emissaries of the Valar?
