[Ciaphas Cain]

Prison is not enough. She needs to be the ONLY prisoner in the entire facility. Which would be on a rocky island a hundred miles from civilization. Food shipments and relief staff every two weeks. The only means of communicating with the outside world a rusty telegraph key manned by an Eagle Scout well versed in Morse code. Drones patrolling the perimeter for twenty miles out. Any unauthorized approach to be met with a merciless blast from the railgun positioned atop the bluffs.

And put her in a mask. Polished beryllium steel like the kind Destro wore would be appropriate.

I’d throw in explosive anklets that wold go off during tampering or getting x distance away from the source.
