Sienna had originally created zombies for a simple reason. She wanted to see how different they were from skeletons, but she never expected the Spatial Farm to react.
After the first zombie was created, the undead already living inside the space began changing as well. Some completely transformed into zombies, while others became strange combinations of zombies and skeletons. They were no longer ordinary undead. They had become Martial Demons.
Their changes were obvious. Their skin and flesh had become extremely tough, comparable to leather armor, while their bones were harder than steel. Their bodies were pale and could not breathe, yet from the outside they still looked like ordinary humans. Only their eyes revealed their true nature, carrying a distinct air of death.
