Sea Bishop

Imagine you’re a fisherman in the 1530s, hauling in your nets somewhere in the Baltic.

It’s cold. The water’s rough. You’re expecting fish.

What you’re not expecting is something in the net that seems to be looking back at you. At first, you think it’s a man.

Then it moves.

Its body spreads strangely, like wet robes drifting in the water. Its limbs aren’t arms, not exactly—but they bend and fold in ways that feel a little too deliberate. And its head…

Well.

It looks like it’s wearing a bishop’s mitre.

You’ve just caught what later gets called the Sea Bishop. Unsettling, right?

It gets worse.

According to the stories, it didn’t thrash around like a normal animal. It didn’t try to bite anyone. It just… watched. Calmly.

One account says the crew tried to keep it alive, but it refused food and died after three days.

Another says they released it—after it made the sign of the cross.

Because apparently that’s a thing you have to deal with now.

Naturally, Renaissance scholars wrote all this down. Guillaume Rondelet. Conrad Gessner. Back then, “natural history” was less about proving things and more about collecting every deeply questionable story you could get your hands on and putting it in a book.

To be fair, there are more sensible explanations.

Flip a ray or a skate over, let it dry out a bit, and it starts to look disturbingly human. Give it the right lighting, a bit of imagination, and suddenly you’ve got something that looks like it should be delivering sermons.

And if nature didn’t quite get you there, people were happy to help. “Jenny Hanivers” were basically DIY sea monsters—real animals carefully cut and dried into something a lot more… marketable.

So yes. The Sea Bishop probably wasn’t an actual underwater clergyman.

But here’s the thing.

When people see something they don’t understand, they don’t describe it—they interpret it. They reach for something familiar. Something that feels like it knows more than they do.

Which raises a slightly uncomfortable possibility.

If multiple people looked at the same creature and went, “Ah, yes, that’s a bishop”…

…what, exactly, was it doing to give them that idea?

If you’ve read Blood in the Water, you already know the answer is: nothing good.

Sea bishops don’t cause chaos. They don’t need to.

When one turned up during the mess hall incident, while everything else with teeth was busy making a mess of the place, it didn’t attack. It didn’t rush. It didn’t even seem particularly interested in the food. It just watched.

Calm. Still. Completely out of place—and somehow the most unsettling thing in the room.

Someone later swore it made a small gesture with one fin before it was recaptured.

Not a blessing. But close enough that nobody present has been entirely comfortable around water since.
