Venli had warned him about this. Voidspren invisibility didn’t work properly in the tower. So it appeared that, to keep an eye on someone here, they’d begun entering an animal’s gemheart. He tried to pretend he hadn’t seen it. Eventually, it turned and scuttled down a different hallway. Voidspren weren’t fully able to control the animals they bonded; though apparently the dumber the animal, the easier they were to influence. So there was no way of telling if the Voidspren had decided it had seen enough for the day, or if its host was merely distracted.
