If the garish exterior of Gregor's palace had thrown Niels' preconceptions, the interior only reaffirmed them. Once inside, Niels could see nothing in the house beyond white walls and a single overhead light in each room.

There was no artwork, no photographs, no sign of a woman, pet, plant, or any possible sign of life.

"I like simplicity," Gregor said. "I don't really like ... things." The word lingered in the air between them.
"Except for an enormous house," Niels smirked.
