Guiltspur is an ongoing excavation of a Thassilonian ruin on Varisia's northern Storval Plateau, begun and driven by the infamous blue dragon Cadrilkasta. The aged wyrm discovered the catacomb only recently and has been unearthing it with the help of enslaved giants and ogres. No one knows what the dragon is searching for, but he (or she, as Cadrilkasta's gender remains unknown) has not let continued attacks by ghosts or deadly skull rippers be a deterrent.
