"Yes, my lord," she says, and she hurries back to her room.
Her very own room. With her very own wonderfully comfortable bed, her very own desk, her very own calligraphy supplies. She settles in and starts writing, copying out a fragment of a poem she likes from memory, then embellishing it to a ridiculous degree and starting again on a new page. It's wonderfully soothing. Easy to lose herself in.
An excellent distraction from how much she wants to sneak back into the Emperor's blank room and touch herself while she thinks about being fucked to death by illusory stone. He'd probably have her gang-raped again. She doesn't fear pain much anymore, but she still fears humiliation, and the chance that the man who hates her will lose his temper and crack her head open and she'll be gone before the Emperor can fix it.
The words and phrases she's writing start to tend in... a direction. She sighs. She abandons a half-finished 'violence' and starts planning a serious piece, a verse of poetry about dragons, arranged and coloured so that the end result will look like the Emperor's eyes. It takes her several hours and successfully gets her to stop thinking about how much she wants him to torture her again.
