As Rita traveled through each of the main cities' teleportation arrays, she left behind a pre-prepared little spider corpse at each stop. This way, she could monitor how many Moonfox soldiers had been dispatched from each city, viewing everything through the spiders' eyes.
After making a full circle, Rita returned to Moonfox City. She changed her clothes—burned them—transformed into a goblin, and sprayed herself with a third bottle of perfume.
She couldn't afford to be careless and didn't want to bring any of this mess back to Earth if possible. Ideally, she wanted to pin this whole situation on Lania Kaia, making the Mistblade Moon Emperor think that the Lania Kaia residents had stolen the books.
