The Scam to Move the Mississippi Headwaters

In 1881, Willard Glazier enacted a scam intended to sell books and make his name immortal: he would find the headwaters of North America’s biggest river, the Mississippi. The trouble was, American geographers already knew where the river’s headwaters were, and had for 50 years thanks to the help of the region’s Ojibwe nation. Glazier […]

The Songhai Prince in Hiding

In the 1580s, a prince of the Songhai Empire in what is today Mali fled into hiding after completing a sensitive mission on behalf of the emperor. He remained undercover for five years, hidden in plain sight, until the coast was clear. Finding the prince without blowing his cover could be a really fun short […]

The North Rona Island Rat Apocalypse

North Rona (or just Rona) is a tiny island in the icy waters far off northern Scotland. Its geography and animal life would make it a cool adventure site on their own, but its real claim to fame is that in 1685, a plague of rats wiped out all human life on the island, with […]

Lop Nor, the Wandering Lake

Lop Nor was a salt lake in the Taklamakan Desert in remote western China. The lake no longer exists; damming the Tarim River to create an agricultural reservoir doomed it. But while Lop Nor existed, it was a terrible puzzle, because every time outsiders visited the lake it seemed to be in a different place. […]

Ben Franklin’s Almanac Prank

In 1730, future American founding father Ben Franklin published his first almanac. While Poor Richard’s Almanack is famous today, Franklin had to do something to stand out in a crowded market. So he used a gimmick: he predicted the death of the author of a rival almanac, then kept the gag going for years, absolutely […]

Herald-Inspectors

The role of the herald in Medieval western Europe was multifaceted: messenger, diplomat, announcer, and an expert in the system of personal and family insignia called “heraldry”. Starting in 1530 in England and Wales, royal heralds were sent out to verify that everyone using a coat of arms was approved to be doing so and […]

PCs on the (Failed Invasion) Battlefield and Coleridge’s Red Herring

In February of 1797, a small French military force landed in Wales. It was farce, easily rolled up by the British defenders. Participating in an invasion based on this one – either as an invader or a defender – is a surprisingly interesting RPG adventure hook! One of the weird events that followed the invasion also makes […]

Five Dead Bodies in an Old Chaco Farmstead

In or around 1030 AD, two women, three babies, and two dogs asphyxiated to death in a farmhouse in a thriving community at the bottom of a canyon in New Mexico. Was this event a tragic accident or was it murder? Modern archaeologists have investigated the site thoroughly and lean towards accident – but it’s still […]

An Investigative Dungeon Crawl in the Royal Art Mine

Herculaneum was a Roman town buried in 79 A.D. by the eruption of the volcano Mt. Vesuvius. These days, it’s a bit of an afterthought to the neighboring buried ruin of Pompeii. But from 1738 to 1748, before excavation began at Pompeii, the excavation at Herculaneum was the big exciting hotness of Europe. Except it […]

By Order of General Ludd and His Luddites

The Luddites were a British labor movement active roughly between 1811 and 1817. They opposed the growing mechanization of the British textile industry by smashing machines, burning buildings, and threatening – and sometimes killing – business leaders and magistrates. They had a secret, probably fictional, leader. And they’re more relevant now than ever. Let’s look at what […]

The Shaman/Detective Team-Up

Uluksuk Mayuk was an Inuinnait (Copper Inuit) shaman active in the early 1900s. In 1914, he heard about a double murder and went to investigate it. Two years later, a Canadian detective arrived unexpectedly from a world away. Uluksuk and the detective pooled their information and their resources, then Uluksuk led the detective to the […]

“No, I’m the Real Martin Guerre!”

In 1548, Basque peasant Martin Guerre disappeared from his village in southwest France, abandoning his wife and child. Eight years later, he returned. Life improved; he was a better husband, father, and member of his community. But Guerre’s uncle brought a lawsuit against him claiming this peasant wasn’t the real Martin Guerre, but a similar-looking […]

The Politics of the First Witches’ Sabbaths

Today, a standard component of the European myth of the witch is that witches are organized. They maintain heretical Satanic sects or covens and form a vast conspiracy to undermine the Christian order. From Faust to The Witch (2015), the idea is almost taken as a given. But it’s actually a pretty new concept. The […]
