Geron basks in the light and noise noise and shudders along with the ship.

He considers the question as to what he wants to have the ship do after he leaves it, then makes a dismissive gesture.

"Pain is just an opportunity for growth. If the ship takes damage-"

The Slaanesh cultist imagines what damage the ship will take and regrets that it currently lacks the ability to feel those wounds.

"Repair it and build it back better. I leave the details of that to the crew, along with the responsibility of imagining the punishments I'll inflict for failure. Just be ready for when I want to leave."

He found claustrophobia combined with a lack of stimulation worked remarkably well as a method of torturing his fellows, once the sensation of fear wore off the boredom was the worse part of it. Failure was the inevitable result of him having to make use of imperfect beings, he just had to decide what speech to give as he sealed whoever ended up needing to be made an example of into a near-airtight alcove.
