A Perfect Circle has existed for four years so far, although officially it begun on a site known as Fallen Shadow Clans Reborn. Over the years there have been many highs and lows, with many cats being born and dying off within the Clans, along with prophecies and battles that have driven them apart as well as drawn them together. Here is the outline of important events taking place on the site, with ones written in red being major plot points.

* Due to when some threads were created, this list is not necessarily written in chronological order, nor do they always line up with the main timeline.

UNSPECIFIED PERIOD: Due to their location, the Clans are faced with many natural disasters that eventually become too difficult to manage. The Clans at the time, ShadeClan, RainClan, BreezeClan, FlameClan, and MistClan decide to split off for their own well-being, with those unwilling to stay heading off in search of a new land. Wolfheart, formerly of MistClan, creates AspenClan in honor of MistClan's previous leader, Aspenstar. They and many ShadeClan and MistClan warriors settle among the aspen and cedar trees. Featherstar, leader of RainClan, settles among the reeds and willow trees, finding the rivers to feel most like home, forming WillowClan. Finally, Flickerstar, along with BreezeClan and FlameClan, make their home within the dense pine forest, with wide open fields offering comfort to those who are accustomed to seeing the stars. This is where they started.

UNSPECIFIED PERIOD: At least fifty years pass between the start of the Clans and the beginning of the site, giving the current Clans very little to no knowledge of past events beyond stories passed down by the elders.
