Glyph Markers

A collection of roughly 1 inch arcane circle markers that I use with maps or 3d terrain in my Dungeons and Dragons campaign. These can represent spells like Glyph of Warding or other magical (or mundane) effects as you desire.

For something a bit larger, check out the two inch wide Arcane Circle: http://www.thingiverse.com/thing:2005828
