Tina stared at the skeleton and asked first.
"Are you... a living soul?"
The skeleton tilted its head this way and that at her question. Eventually, it shook its head to say no.
"...What is the substance that forms the basis of you?"
The skeleton used its bony finger to scribble on the ground.
[Divinity.]
That sounded about right.
A normal undead was usually a summoned creature and most of the time, its physical body consisted of demonic energy. That was why Necromancers preferred to utilise the existing physical body to preserve their demonic energy reserve rather than summon a fully-realised undead from the get-go.
However, this story only applied to the 'physical body', of course.
"What about the soul?"
The skeleton shook its head and scribbled on the ground with its finger once more.
[We are newly created existences.]
"Meaning, you don't have a soul? How can you have ego in that case?"
