It’s not a barbarous jape, Moira Rose. It’s the Ten Plagues. Which, actually, do seem barbarous. But are certainly not a jape (a practical joke).

So. The Plagues. There’s Blood in the water, Frogs everywhere, Lice (or maybe gnats), Wild Beasts/Swarm, Pestilence, Boils, Hail, Locusts, Darkness and Death of the First Born.
