Hundreds of years ago, Camelot grew up around Omphale, the sacred stone of the Universe. Its walls reliably kept the relic from the encroachment of dark forces until Darkan, the disembodied ruler of the world of Darkness, found a way to penetrate the city. To do this, Darkan wins over to his side one of the brothers who came from the Wisdom family, which has ruled Camelot since the time of the legendary King Arthur. After all, only the prince of the blood can remove the magic seal on the city gates. But the second brother stands in the way of the dark lord, and with him the powerful dredges of the four earthly worlds and the knights of the Order of the Shadow. The great battle - brother against brother, Shadow against Darkness - can plunge the Universe into chaos, and its outcome depends not so much on the power of weapons, but on the result of an intricate magical game. Whoever wins the game will win the battle! But which of the two is Prince Eden or Prince Richard? Good or Evil?
