[David Johnston2]

Large humpbacked hairless predator.
Flying creatures like bits of animate darkness and falcon-like talons that rake you as they zip past.
What looks at first like a giant snake with a body nearly as a wide as that of a human being, but as it slides forward without wiggling, you see that its central body is bloated like a limbless diplodocus.
Two twin boys with reptilian scales and eyes and sharp carnivorous teeth, each absently clutching evangelical pamphets denouncing practitioners of magic. They claim that the giant monster was their elder brother.

All of them are averse to sunlight and can be exorcised by very bright magical light.
