Wait - if Hircine created teh skyforge for his followers to make better hunting weapons, that implies that Hircine had adherents amongst the snow elves.
Is Hircine an 'elfen' diety?
Also - if there were Hircine followers amongst the snow elves, but the snow elves were terrified of the skyforge, why did he create it? Remember, the skyforge predates the arrival of the nords.
I can't find anything in the wiki about him being a elven deity, but it does say that he was discovered later then the other daedric princes. So he could have been influencing the mortal realm since the start of time but was not noted in any writings, and he could have influenced elves long before man. Leading me to think that perhaps something happened to encourage Hircine to create a forge capable of creating weapons that are more deadly to elves( perhaps it was an elf who first defeated Hiricne or something? )
And if this
theroy is correct then the companions would have picked up on this fear of the Skyforge( as stated above in another post ) and would have utilized it for defeating the snow elves. But I'm just throwen an idea out there.

But why would the first Companions be drawn to something Hircine was behind? They weren't werewolves back then. That came much later.
Yes but they would have noticed the fear that the snow elves had for the Skyforge and would have used it to strengthen the fight against the elves.

Doesn't mean that they knew it was tied to Hiricne ( if it is tied to Hiricne ).
