Snowhead Blacksmiths
These smiths that live in the Mountain Village will do any odd job. You can forge some great swords with the help of these men. However, some very special powder called Gold Dust is needed to make some of the most powerful swords. One of the men is called Zubora, and has a very chirpy personality. He has a hulking assistant Gabora who seems to be the one who does all the forging while his superior chills whilst drinking a warm drink. Together they make one odd bunch both with very distinct personalities.
It is possible that they somewhen went to the dark side and to Hyrule soemtime before the events of the Great Flood, as in The Legend of Zelda: Twilight Princess, the text of Phantom Ganon's sword reads Zubora Gabora in Hylian.
