Seven Favorites. Their mission is to solve the greatest mystery in history. They came from different eras. And they don't know anything about each other. Some were chosen by the gods for a great cause, others got here by mistake. They are waiting for a journey that will allow them to go beyond fantasy. But before Briseida, the youngest of them, will face a real nightmare - the Eternal Citadel - the greatest master of illusions, where creatures that can penetrate reality from dreams live. When the hourglass flips and the temporary staircases take the heroes to other eras, Briseide will have to believe in legends to survive. But how do you defeat the elusive dark forces who have vowed to destroy her?
