Time travel took place in my world, and when that happens things tend to get complicated. This section is dedicated to explaining what time travel looked like in this world, and where each story took place.
In the Pre-Season of Trailblazers (a game I ran with friends and didn't publish that lasted near 400 hours) my players played in the T1 timeline. They concluded their adventure by going back in time from 4 to 1. This created a branch in the timeline that shared a past with T1 but continued on to have a different future. The altered moment is that the party did not die in the blizzard on their way to Korhal. Thusly Mana was alive for Valerian to marry, and he did not need to go to the south so he did not die. Jadis never came back to life and thus did not destroy the world.
In Season 1 of Trailblazers (a game I published on my podcast) my players played in the T2 timeline.
In between Season 1 and Season 2 Hope made a wish at 3 (many years after the end of season 1) that transported her to the T1 timeline with my players of Season 2.
In Season 2 of Trailblazers my players (unknowingly) played in the T1 timeline. They played far in the future, after 4 where my Pre-Season players had left the world in a destroyed and ruined state that was doomed to die in many ways. My Season 2 players traveled back in time to 2. This created a branch in the timeline that shared a past with T2 but continued on to have a different future. The altered moment is that the Calamity in the Sky has appeared and is waging war with the world (this moment is after Season 1, but before Mana is assassinated).
T1's world is now desolate and empty, with no life of any kind.
T2's world is a world still fighting in a hopeless war against the endless Clockwork who are burning the forests down and killing all who inhabit the planet.
T3's world is now where Season 3 takes place (note it's section hasn't been colored because Season 3 has yet to be made).
