Bab 1488: The First Plague

Sunny felt a headache approaching. 

Something was very wrong here. 

How could the Six Plagues exist? 

The Great River was a time loop — just like Aletheia's Island had been, but also different. 

On Aletheia's Island, time moved in a circle. A single day endlessly repeated itself, and a new cycle started each time that day ended. The Great River, however, was a bizarre place where time and space were one and the same — it flowed from the future into the past, and so, those who traveled it were also traveling across time. 

The cycles of the Great River did not start once a certain period of time passed. They were both a measure of time and a measure of space — to reach a new revolution, a person had to travel all the way to the Estuary, which was also the Source, and cross the boundary between the past and the future.
