They reached the base of the tower, an impressive building several thousand feet in height built entirely of bones. Not the most practical of building materials, it has to be said, and the walls had been progressively strengthened over the intervening centuries. In the seventeenth century, souls bound to the skeletons and interlocked to form a coherent whole. This steadied the whole structure until the Industrial Revolution provided the demons with an underlying structure of steel which was less prone to rust in Dis than it was in the outlying circles. The self-aware skeletons were largely for show these days.
Devious pulled at Jasfoup's trailing wing and pointed at the walls. "How are these different from zombies? They're soul that have been attached to skeleton and made self-aware."
"There's every difference." Jasfoup rapped of a skull with his knuckles. "You can't have animated skeletons thanks to the lack of muscle tissue. They're not driven by hunger in the way ex-mortals are. There's no point. A zombie's greatest threat, apart from a shotgun blast to the chest, is the deterioration of his body mass and internal organs which can only be delayed by them consuming fresh tissue to replace that which has decayed. That drives them to hunt the living. Most go for the brains first to replenish their own self identity." He stood back at stared upwards. "That's why zombies love to eat family members. Shared memories reinforce their own, see?"
Devious shook his head. "Not really."
