The vislae’s road has many steps. Shadow. Satyrine. The Path of Suns and the worlds of the Actuality. But are there even greater mysteries? Further steps? Deeper secrets to reality? Yes. Visla at the height of power and understanding eventually seek the Labyrinth. To enter the Labyrinth is to leave the Actuality forever. Perhaps to die, or worse. Or perhaps to transcend; to find oneself upon new shores. Entering the Labyrinth requires the highest mastery of magical power, knowledge, and skill. Few vislae can truly aspire to it, and even fewer succeed.
