I've had another encounter with Taze, the man I saw at the mayors house back in town. We stumbled upon his portable tower on the way to the copper mines, a pillar of dark stone with a seemingly illusory effect which changes its appearance relative to your position. His wrought iron gates heralded the symbol of Shale.
After speaking with Taze we learned there's been a large scale kidnapping of local mages within Beddegar. This seems to match up with the local wizard who's home Noel and Dok investigated. I'll have to ask them for more information, since it seems like our only current clue as to these kidnappings.
