The 25th Century is a span of 100 Earth years that started in 2401. The current year, 2411, is set in this century, which will end with the year 2501. So far, the 25th century is marked by large-scale conflicts among Alpha and Beta Quadrant powers, as well as many power struggles initiated by the Iconians and their many voluntary and involuntary servitor races.

The conflict ends in the nick of time in Earth orbit, when the World Heart - which was previously retrieved with Krenim time travel technology - was traded for peace aboard the Iconian flagship.
