[Eomer of the Rohirrim]

Gil-galad, Wargs are far older than Orcs. I believe that Orcs could only mould those Wargs already corrupted by Morgoth, the most powerful.

Formendacil, a brilliant observation. Remember the mysterious green hue on the hill when the Fellowship were assailed by Wargs? Possibly Sting related; maybe Sting was an especially mighty sword, powerful enough to call for help from the hilltops, such was the danger the Fellowship faced at that time.

My search for a tale thus far has been entertaining; Elrond's libraries are highly interesting. Though, of course, you have to be wary enough to sift through the lies that Elrond spreads when Wargs are the the topic. Remember that this thread throws doubt on Elrond's nobility that you don't usually find in books on Tolkien.
