It is period of high tension in the galaxy. The
Galactic Empire has sent Queen Trios of
Shu-Torun to Jedha in an attempt to collect the
remaining weapon-powering kyber crystals that
survived the Death Star's attack.
Meanwhile, Rebel leaders Princess Leia and Luke
Skywalker, joined by smuggler Han Solo, have met
with the surviving members of Saw Gerrera's
Partisans. The group is led by the Tognath named
Benthic, to whom the rebels offer supplies to help
the natives cause.
But when General Kanchar of the Empire drops an
orbital drill onto the planet, destroying more
homes of the struggling civilian survivors, the
heroes of the Rebellion decide it's time to bring
the fight to the Imperials....
↑In Star Wars 43Trios says that "the Imperials are weaker than they have been for twenty years," meaning it must take place at least twenty years after the formation of the Galactic Empire, which Star Wars: Galactic Atlas dates to 19 BBY. This means Star Wars 43 takes place no earlier than 1 ABY. The issue is also set before the Assault on the Mako-Ta Space Docks, which took place in 1 ABY, it must have occurred in 1 ABY. This issue is part of the same story arc and takes place immediately before Star Wars 43. Therefore, it also takes place in 1 ABY.
