There are currently ten known Power Sigils, each used to tap into a unique aspect of the realm's energy through dice-like Di-Gata Stones.
Individually, each Sigil is capable of unleashing a burst of raw energy, but when used in combination with each other, the energy aspects blend together to form a Henge. Not only does this create a far greater concentration of power, it also allows access to other kinds of destructive or helpful powers. These sigils are also inscribed on various locations, objects, articles of clothing and sometimes as birthmarks or tattoos on the people's faces (like Brackus' Infinis tattoo on his forehead).
To study the Sigils one must first realize that no sigil is evil and no sigil is good. The sigils transcend these moralistic notions, they represent parts of the whole and could never exist without their opposites. It is through the combination of Sigils that one creates true power, this is why pupils focus their study on two sigils, a single sigil is of limited value and power on its own.
