Erik clung to a piece of debris orbiting Uncle Benjamin. The man kept that and many other things, including human bodies, close to him so that he could use them to attack.
What he needed human bodies for was unknown—maybe to look more scary.
The makeshift shield rotated at dizzying speeds around the man, a whirlwind of concrete, metal, brick, and disgusting things.
The rotating shield was a masterful defensive strategy on Levium's part.
The thing was very effective for several reasons. First, it was unpredictable and always moving.
This made it hard for attackers to hit Uncle Benjamin directly. Any attacks would likely be blocked or broken by the spinning debris.
Second, the fast rotation created a blurry effect. This made it hard to see where Uncle Benjamin was, so enemies couldn't aim at him.
