Shimmer is back. Two years after the war with Noxus had ended, a new gangster emerges within the undercity, now known as 'Zaun'. Daunter is a ruthless chem-baron who has reformed the city's drug empire. He refloods the streets with shimmer and gains the title 'Silco's Heir'. The Firelights are back in commission after two years of lax, taking down exports just like the days when Silco was still alive. When the group arrives at an export and finds it already taken down with the barrels drained of shimmer, it becomes apparent that Daunter and his gang aren't the only ones they need to look out for. They had competition. Or... did they? Ekko finds himself involved in a seemingly endless cat-and-mouse chase with another gang leader-a woman who moves like the wind. He wants to know what her motives are, but he has to catch her first.
