I’ve gone ahead and updated our Spirit Tracks Characters section of the website. It includes the several characters that were featured at the UK official website, numerous characters that were mentioned in the revealed storyline over at IGN, as well as a couple other characters found within the various Spirit Tracks trailers.
Some of the descriptions, as well as the images, are very speculative and have not been confirmed quite yet. If you see something that interests you, or perhaps think we have missed something. Head on over to our Zelda Forums and let us know.
