Weird Treasure: Letters of Introduction

In the seventeenth century, an Iraqi named Elias al-Mûsili traveled throughout Latin America, armed with a thick stack of letters of introduction from some very prestigious people. With these letters, he was welcome just about anywhere ruled by Spain – and he accumulated more letters as he went. Historically, letters of introduction were boilerplate, a […]

Madame Chouteau’s Clever Frontier Inheritance

Marie-Thérèse Chouteau was one of the founders of the city of St. Louis, Missouri. She was a powerful and unusual woman, existing both inside the Franco-Spanish colonial system and outside it, depending on what suited her needs. The way she obtained her inheritance from her not-husband screams to be turned into an adventure, and she […]

Apostolic Succession, Donatism, and the Hidden Pope

We got a weird one this week, folks! This time, we’re going to look at the principle of apostolic succession in the Catholic Church, how it underpins the authority of the pope, how that triggered a revolt in the fourth century, how it impacted the Western Schism of 1378-1429 when there were three rival popes […]

PCs on the Battlefield: the Siege of Cartagena

The 1741 siege of Cartagena, in what is today Colombia, featured a really interesting variation on the normal siege framework. The British attackers knew going into it that they would likely suffer a devastating outbreak of yellow fever, and that the Spanish defenders would likely be unaffected. Thus, they were racing the clock: they had […]

The Trans Conquistador, Lieutenant Erauso

This week we’re going to look at a series of bloody, hair-raising adventures from the autobiography of a 17th-century nun, conquistador, murderer, and transman. Lieutenant Erauso was a celebrity in his own day, and his tales of mischief and mayhem across South America make terrific templates for RPG adventures! I’ll talk more about identifying Erauso […]

The Glass Delusion

The glass delusion was a weird pathology common in the late Middle Ages and Renaissance where the afflicted believed they were made of glass. It was also popular in literature, with some interesting changes to make it more suitable for fiction. The whole thing – history and fiction both – is super gameable! This post is […]

Sentenced to Burn in Effigy

We’re all broadly familiar with the Spanish Inquisition, that fanatical office of the Spanish monarchy that used the Church to hunt down anyone who deviated from Catholicism. And we all know how fond the Inquisition was of burning people at the stake. But what did they do when somebody needed burning, but wasn’t around to […]

Carving Up Spain

This is not a post about the War of the Spanish Succession (1701-1714). That would be long and boring and not gameable. This is a post about the political crisis that led to the war – which is long and interesting and very gameable! Stick with me, folks, because this is going to get weird! This […]

The Secret Basque Fishing Grounds

In the high Middle Ages, the Basques – an insular people of western Europe – quietly experienced an economic miracle. Basque fishermen brought huge quantities of preserved cod and whale meat from secret fishing grounds somewhere in the Atlantic. As Basque communities prospered, the rest of Europe scratched its head. Figuring out where the Basques were getting […]

A Logic Puzzle on the Ebro Delta

This week, we have a cool logic puzzle that can be easily inserted into any ocean journey! Failing to solve it has memorable (but not catastrophic) consequences. And at the end, we have a way to turn the logic puzzle into the start of an easy-to-improvise adventure! Noted sailor, writer, and delightful liar Tristan Jones […]
