Aster POV;
Yesterday, Seraphine got bitten by an insect, but that kind of bite isn't a common mosquito, it's a parasite that is controlled by someone, bred from a laboratory and then linked psych energy to it, in order to control it.
I know this Parasite since...well, our Queendom is the one that developed it. But mind you, my mother was against this since it is torture and against her code or morality, so she ordered for it to be destroyed.
It was a long time ago, and she ordered for the destruction of that parasite even before Celestia became an Empire.
Of course, my mother knew that some people kept the parasite, either as a keepsake or something else, but my mother made sure ALL the parasites were destroyed within Celestia and the Star Queendom.
So who kept a parasite? And not only that they used it on Seraphine! I didn't sense any sort of strange presence, since there were a lot of people that were walking around.
