Arcane season 2 puts more focus on Ambessa Medarda, a character who is manipulating Piltover’s remaining council members for her own means. In Arcane season 1’s ending, Jinx changed the war between the wealthy nation of Piltover and its destitute undercity of Zaun forever. Jinx’s attack on Piltover’s seat of power removed any chance of peace between the two cities, fueling a revenge quest filled with rage and anger that will now be spearheaded by Piltover’s new general, Caitlyn Kiramman, as of Arcane season 2, Act I’s ending.
