Richard lives in Hartland right? isn't Hartland a land were magic does not exist? if so, how did Kahlan confess the solider at the cliff, and how did zed heal Richard and reveal the Sword of Truth?

Magic didn't 'exist' because nobody with magical powers had crossed the boundary, that's why it was there... It doesn't mean bạn can't do magic in Hartland -_-

In the Episode where Richard killed Ransyn Fane, the one who took the Book of Counted Shadows, he unleashed the magic of the sword. Thus, magic has been used.

Well, in the books, the boundaries were actually put up bởi Zedd when he was younger. The first boundary he put up was between D'Hara and the Midlands because he had just killed Darken's father and left Darken with horrible scars on his torso. After that, when he found out that his daughter was pregnant. He fled to Westland and put up the boundary for people who no longer wanted anything to do with magic. So, Westland can be affected bởi magic, its just that no one but Zedd was there to do the magic.

Everybody just thought that magic didn't exist there but it did. Kahlan crossed the border.

u can use magic in hartland just nobody but zedd and kahlan can cause their the only ones with magic there
