Rise of the Runelords (Candy)
According to Brodert Quink the seven-pointed star from the Thassilonian Empire represented not only the empire itself but also the Seven Virtues of Rule: Honest Wealth, Rest, Eager Striving, Fertility, Sincere Satisfaction, Righteous Anger and Abundance; and the Seven Schools of Thassilonian Magic: Transmutation, Conjuration, Abjuration, Enchantment, Illusion, Evocation and Necromancy.
The Seven Virtues of Rule seem to have been perverted by Thassilonian rulers into the modern Seven Deadly Sins.
According to local scholar Brodert Quint, this seven-pointed star-rune was a very powerful symbol of Thassilonian arcane magic.
