Dark Ore Salesman

The Dark Ore Salesman is a character from The Legend of Zelda: Spirit Tracks. He is, as his name implies, a seller of Dark Ore, an extremely valuable substance that melts when exposed to light. He will sell Dark Ore to Link, which can be brought to Linebeck III for a Force Gem. To reach him, however, a tunnel containing a Rocktite must be taken.
