You heard it here first. Terry Goodkind, author of the highly successful Sword of Truth series, is to make a guest appearance in a future episode of Legend of the Seeker, which is based on his novels.
Goodkind will play Tobias Brogan, a character from his third novel Blood of the Fold. Brogan is the Lord General of the Blood of the Fold, a fanatical group of witch hunters who wish to expunge all magic from the face of the earth (and those who have the gift are tortured and murdered).
It is unclear whether or not Brogan will be a major or minor part in the third season of Legend of the Seeker, or if his role will continue for more than one episode. In the novel, Brogan is responsible for kidnapping Kahlan Amnell, but there is no confirmation if this plot device will be used.
UPDATE: This post was an April Fool's Day prank. There is no evidence that Terry Goodkind will appear in Legend of the Seeker, that Tobias Brogan will appear, or even that Season 3 will happen.
