So, Librie literally went all out on her master plan which had like 10 years on the making, first try to kill the War God of her tribe so if Pereia decides to attack they'll be defenseless against their War God's, kill her husband so that she loses all the power she had herself as the second mother, try to kill Pere so (If he had died) there's no one to blame for the deaths, poison Orca having enough faith on a group of traitors from another kingdom so that you don't check the antidote effectiveness considering she had it for years, truly a special mind at play, she literally made all the correct moves to get fcked.
