Abomination of bones

"Ready to welcome some more brothers?" Athos asked, looking at one of the randomly arranged skulls.

The bone abomination snapped the bones in agreement and Athos began to fuse the skeletons one by one. His body grew in size and power, until it looked like a small hill. When Athos ended, the bone abomination had grown to nearly fifty feet, and its cores looked like a constellation, with several small black cores connected by life force threads to a central core.

"You have enough mass now, let's change your shape a little." Athos spoke and cast the bone craftsman into the abomination of bones. The abomination continued to look curiously at Athos, feeling its shape slowly change.
