“I’m sorry, I don’t know how.” She said to the voice. “As for your body, I don’t think that it’s anywhere near here. The fighting at the city ended yesterday, or the day before I think. But we’ve already moved several miles away to a small fortress.”
The voice sounded shocked,
"Yesterday? No... No that can't be... I've been in here for nearly a week at least!"
Now the voice sounded angry,
"don't try to confuse me, devil! I don't know what games you're playing but it ends now. Show yourself and face me you coward!"
Colorful insults followed.

He practiced the process several times on a woman in her fifties, trapping her soul in a crystal while he experimented on puppeteering her living body with his magic. Even though she had a sturdy constitution the effects of the void on her body were apparent, black veins appeared on her flesh and her skin turned grey until she eventually rotted away into undeath.
The void was a volatile substance and deadly to the human body, including those who wield it. Over many years he'd developed a tolerance, but it would still eventually kill him if he were so exposed.
He needed an intermediary, something infused with the void that could introduce his magic to the body in such a way that would give him control without consuming the life in the body.
He went to the uninhabited body of the assassin and placed a cold hand on her bare stomach. He knew her muscles beneath the fair skin were strong like corded rope, but even she couldn't withstand the void for long. If he could find a way to transport magical constructs and other such things into these dimensional spaces he could translate the void into something less caustic to the human life force...
Programming magic on objects was the basics of enchantments and charms. But it was often limited since common practices of enchantments were simply spells placed on the object itself and finely tuned so as not to destroy the object with its power.
But if enchanted objects could be transported into the crystal in addition to enchantments on the surface... The potential was vast if such a theory bore out to be true.
Well, after checking her hand and finding the rock missing he knew it was possible to some degree. Once
Diyah returned with her report he could move the project further.
After an hour he returned her soul to her imprisoned body.
