The Circle Rune is a complete mystery among the 27 True Runes. It is said that this rune governs order and stagnation, and is therefore the symbol of balance. Harmonia's capital building, the Circle Palace, was likely built as some kind of tribute to this rune's longstanding power. The current bearer is the ruler of Harmonia, High Priest Hikusaak, and he has borne the rune since the Hero's War in Aronia in SY -2. However, neither Hikusaak nor his rune have been seen in hundreds of years, leading many to speculate that Hikusaak is long since dead and the rune has been missing from Harmonia for some time.
