The queen-mother Seelima's first big breakthrough came when she managed to make the king send one of the queen's cronies in the harem to a sadistic noble using some false allegations and honeyed words.
And after her first triumph, soon more success followed.
Later, another one of her bullies would mysteriously fall off a window.
Another would somehow earn the king's ire and be torn by the dogs limb to limb.
In this way, she would use the fact that she had the king's ears and even his eyes to exchange favors with the nobles, helping her eliminate her targets while she whispered little suggestions, telling an event a certain way, and even knowing about various secret treaties.
Hence, slowly and carefully she made the king's harem her own kingdom, kicking out the queen and relegating her to a sideshow.
And after that came her revenge arc, where she made every single woman that harmed her taste their own medicine, the best example being the queen herself.
