Eye of Andrion

A brass medallion with a center of clear crystal found by Sandre, after learning that the magus Davin was looking for it. The medallion is inscribed with the Verditius runes for Intellego Vim.

In the summer of 1196, Sandre and Agnes discovered that the Eye can cast Sight of the Active Magics (InVi 40) three times per day, with zero Penetration.
To do this research they performed several experiments, one of which resulted in them seeing a ghostly maga through the Eye.

The Eye belongs to Sandre, though he might let another magus borrow it.
