Imagine that a deer is killed, its head chopped off and eaten, and a bunny is killed, its body is eaten, and its head is left behind.
When all of this Bone horror stuff started, The deer and rabbit would re-animate, and join together, resulting in a deer with a bunny's head.
Over time, more dead parts will join this monstrosity.
The example above applies to all (once) living things on aloria, Skeletal fish roam the seas alongside rotting sea serpents. The tattered wings of long dead dragons try to take flight as they fruitlessly flap in the hot desert air. The once still forms of slain men on the battlefield roll towards each other, a demon with legs for fingers and heads for eyes rises in their wake. Frankensteins monster now seems like a plush compared to these abnormal creatures. Any attempts at communication fail, and conventional weapons unable to do lasting damage against the dead foes. For they are not comparable to the undead that has haunted aloria for all these years. No, these are comparable to automations, set out to do their masters bidding!
