A bunch of workers sit in a large shared office, hard at work. One of them has a writhing mass of wormholes, politicians, and plasma, with a rope around it, tethered to a steel ring by their chair. It bounces around the office, sometimes fast, sometimes rapidly.
When it bumps into a living being it tries to kind of merge with them. It enters their body, their eyes get an unearthly hue, and they drop their work and start fervently trying to convince people of strange things, occasionally surreptitiously sabotaging things or assassinating people, and leaving spy devices and malware everywhere they go.
