A series of disparate fragments of crystal and destroyed buildings that are locked in place scattered over the sky of Philosophia. They appear nearly invisible to the naked eye during daytime due to their relatively small size and high elevation, but sparkle like stars in the sky during nighttime.
The dragontears were created as a result of a great battle in the skies of Philosophia, believed to have been a great wizard’s ad-hoc defence against enemy dragons. Any huge creature such as a dragon that attempts to fly through this barrier will be riddled with wounds as the dragontears penetrate through them or stop them in their path entirely.
The defensive nature of the dragontears contributes to the belief the city is uninvadable.
