The Circle of Magic (Spoilers all books incl City of Dragons)

['thul]

Quite simple. Defaced glyph up, left or right. Pit down. result = pit trap.

That tree-knee hated the wit indicates that he was after the time of the piebald prince. or perhaps even during that time. Because the six duchies folk did not understand, or at least forgot, the link between the different magics, they were treated differently. the wit, was by many seen as bestial, the skill "high", hedge magics and such as strange/occult.

if you want one of those crazy theories, then imagine that the skillmasters knew perfectly well what the wit was and did not dislike it for being bestial but for being used on the wrong targets. If a magic is designed for dragon communications, would you not find it abuse if it was used to talk to a mere dog/horse/cat/etc?
