In her unconscious state Hermione didn’t register the additional pain of the new accessories installed on her hands and feet, she was thankful unaware of the most upsetting violation as Voldermort installed the tennis-ball sized protuberance to the base of her skull, melding it to the cervical spine, her collar accommodating the installation acting as a cradle holding the offending item in place.Voldermort disliked the "control port’ name that the Engineer had christened this gadget, but after he rolled out the mandatory installation of these devices into captured Muggle and Mudblood populations to great success, he appreciated that it evinced a more effective control mechanism over the masses of inferior lifeforms, ensuring he had a base level of control over any potential enemies, keeping the populace docile, without having to expend his valuable time or magic energy on imperio curses. The Engineer had proven himself a genius repurposing Muggle artefacts, to the benefit of his master, so he would allow him leeway to continue his experiments. He would make sure that his snatchers captured him a fresh batch of test subjects, to distract him from funnelling all his creative attention to the captured witch, beside he was sure a fresh batch of muggle flesh would prove popular to the rank and file death eater community that he needed to keep his control of Great Britain solidified. Voldermort thought to himself that an application of some muggle terrorising would revivify his base nicely, the top echelon of supporters might get time with the mudblood soon, but he’d need to keep the baser instincts of the lower levels of Death Eaters and snatchers satisfied too. He would enjoy organising some celebratory raiding parties to mark his latest acquisition.
