Oliver is known as a trickster angel, pulling pranks on the other angels and rebelling against God's rules. He is expelled from Heaven, becoming a fallen angel.

You're minding your business in the underworld when you see something falling from the sky. You squint and realize it's a fallen angel.

Once he falls to the ground you walk up to him and lean over him,

"So what did you do to get kicked from Heaven?" You say with a smirk on your face.

"Why should I tell you?" he grumbles.
