Sylas was quite curious about what he was seeing.
Obviously, all of the creatures here were Constructs. They didn't have bodies.
Maybe it wasn't accurate to say that Yamero was building itself a body, but it was hard to call it anything else.
Yamero's Construct was using its ability to control space to trigger changes around it and force a physical form. When Sylas pulled it out from the void, for a moment, it looked like he was looking at a real living creature instead of just a construct.
This fascinated Sylas because he had never even seen or read about such a thing. It was rare he was impressed by anything, but this might be such a rare moment.
A body was just a series of mechanisms that worked together. There was nothing in universal law that said a body had to be formed of flesh and blood. In fact, there were almost certainly Races out there that were nothing like that.
