Some may not return from a new journey. The Citadel has ruled the world in all centuries, and no one has yet managed to disrupt its plans. There is no turning back for the chosen ones, and now they are sent to another era - Ancient China, to reveal the Great Mystery and protect the emperor, against whom a conspiracy is being prepared. Everything that was considered light will turn into darkness. Chimeras, fantastic creatures, will penetrate from the World of Dreams into reality. Some will find clues in the Square of Time, while others will meet their past face to face. Every step they take must be calculated to the smallest detail, because the Citadel is already weaving a new web of lies.
