The Time Cycle is a mysterious phenomenon observed in the fabric of spacetime. First documented by the renowned Chronos Institute of Temporal Anomalies, it appears as a localized distortion of the timestream.
Initial observations suggested that the Time Cycle was a natural occurrence, akin to a localized whirlpool in the ocean of time. However, further study revealed that it was actually caused by an ancient civilization's attempt to construct a time machine.
The first recorded instance of the Time Cycle was in 3456 BCE, when the Chrono Institute attempted to break the 300-second barrier, creating a rift in the fabric of spacetime.
Since then, numerous attempts have been made to harness the power of the Time Cycle, but all have ended in disaster. The Time Splinter incident in 1987 CE resulted in a 4-year gap in the timeline, while the Time Sphere experiment in 2099 CE created a pocket universe.
Today, the Time Cycle remains a subject of intense study and speculation. Some believe it's a doorway to other dimensions, while others see it as a mere anomaly in the fabric of spacetime.
