Dracia Eldren was a sharp featured woman. Her long greying hair was pulled back into a severe coif. Narrowed black eyes studied the potential Princess stand-ins. Darcia was well schooled in the ways of ettiquette. She was a seasoned Mistress. Her name was well known about the different Kingdoms and Queendoms.
She was the woman you contacted when you wanted your daughter to become the well cultured and well taught pillar of nobility. She was the woman who schooled young princesses on the fine art of being noble. Dracia was as strict as they come. Years of practice allowed her to use a switch upon her subject without leaving any marks. Only a sharp stinging pain as a reminder of their failures. She lives for her work.
If you wanted to infiltrate a kingdom with a doppleganger…you needed the help of a professional. One who knew all the ends and outs of Princess behavior.
Her dark grey coat hardly never touched the ground as she walked. Her back arched and her head held up proudly. Darcia fingered the switch at her side as she studied these potentials. These potentials were of poor condition. Some of them were farmer’s daughters. Pathetic. She had her work cut out for her. At all times there would need to be at least three princess replacements in training. They would have to learn together. Eat together and train together. Every movement would have to be perfect. And she only tolerated perfection.
In nature, for instance, a rhino has flies and ticks etc, that live on the hide and live off the blood. Rhino will visit and lie in ponds where turtles will clean the underwater portion of the ticks and a species of bird will clean the the top of ticks and other parasites. What if where the characters camp there were a species of animals that lived off wounds of the creatures. PCs camp. Anybody with wounds on there body are soon covered with small rodent - insect - shadows - whatever. Would immediately see it as a threat I would imagine. But perhaps one of the wounded didn't wake up when it happened, and when they did finally wake they were completely healed. Perhaps somebody was warned of something attacking them but they were able to notice that the wound was actually getting smaller instead of larger. Or maybe they successfully beat the creatures off them and don't notice an improvement, marking this place never to rest at ever again....later learn that villagers send their wounded there but they keep it a guarded secret because they don't want all the attention or traffic and what comes with such a special gift. Could turn into something more too if characters decide to start blabbing about it.
