GQFW rise of the rune lords
This seven pointed star was used by the ancient Thassilonians to symbolize the seven virtues and the schools of magic associated with them. As the Rune Lords became corrupt the seven virtues turned into seven vices. It was also discovered that if someone was to have the Sihedron tattooed on them before death their soul would be sent to the nearest runewell that matches the sins of the deceased. The Sihedron has been been found in many Thassilonian ruins all up and down the Lost Coast.
