Rhizocephala, the parasitic barnacles (here Peltogaster paguri, a hermit-crab parasite)

The King of Cups sits on a stone throne in the middle of a rough sea, perfectly calm, cup in one hand and scepter in the other. He is emotional control, the ruler who governs feeling instead of drowning in it.

The rhizocephalans are barnacles that gave up the shell and the fixed spot on the rock for a stranger kind of power. A female larva finds a crab (or, for Peltogaster, a hermit crab) and injects a few cells. Those cells grow into a network of rootlets that spreads through the host's body, and then a sac pushes out under the crab's abdomen, right where the crab would carry its own eggs. The crab stops reproducing and stops molting, and tends the parasite's brood as tenderly as if it were its own. Males can be pushed into female behavior. This isn't one tyrant. It's a law, repeated across many species: govern a body from the inside until it serves another lineage and calls that love.

That's why the King gets the whole group and the Devil keeps one species. The Devil is possession, which is loud. The King is administration, which is quiet and far more effective. His gift is real: the ability to hold steady and make others steady. His shadow is control so deep and so polite that the governed can't tell which feelings are theirs. The crab isn't suffering, as far as anyone can tell. It's busy. It's caring for its children. That is the horror, and also, if you are honest, a fair description of a lot of happy lives.

So when the King appears, ask who wrote the emotional rules where you live, and whether they're followed because they're good or because they've taken root.

Scene: a calm king on a stone throne in a gray sea, cup raised, and beneath the water, fine golden roots spreading from his throne into the rocks and the crabs below.

Prompt: Whose emotional rules do you live by? Write down three, and the name of whoever wrote each one. Then write which of them you'd keep if you found out.
