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. […]

Weirder Xenomorphs: Strepsipteran Insects

You know the alien from the movie Alien? The creepy, scary one with the shiny black carapace and the chest-bursting larval form and the well-regarded RPG by Free League? If you’re like me, you want to put that monster (the ‘xenomorph’) in your ongoing campaign, but you don’t want to use exactly that same monster; […]

Scholarly NPCs from Aubrey’s Lives

Last month we looked at nine bizarre occult NPCs from 1600s Britain, taken from a wonderful historical source: Aubrey’s Brief Lives. This week we return to the Lives for eleven scholarly NPCs, and – as before – we’re less interested in the real biographies of these people than in the gossip Aubrey reports about them. One […]

Four Machine Puzzle Rooms

This week, I’m deviating from the blog’s usual history-and-folklore content! Instead, let’s talk about four simple pieces of hardware and how they work: a faucet, a rotary vane pump, a pin tumbler lock, and a chain hoist. Each works in a clever fashion, and when enlarged to the size of a room, it has components […]

The Point Lake Diamond Rush: Spy vs. Spy

When diamonds were discovered in the tundra of the Barren Grounds in far northern Canada, it set off a chain of secrets, deceptions, covert actions, and industrial espionage that make an amazing template for an RPG adventure. Even if you’re not running an actual espionage campaign, PCs could be easily hired on as deniable assets […]

The Fossil ‘Ida’ and Science by Press Release

In 2009, the Natural History Museum at the University of Oslo announced the discovery of a new fossil of an ancient, extinct primate. The discovery was published in a normal peer-reviewed scientific journal, but was accompanied by the simultaneous release of a book and a documentary. These, like the press conference (but unlike the paper) […]

Epic Tier Threat: The Year Without a Summer

In 1815, Mount Tambora in modern-day Indonesia erupted catastrophically. The ash and gasses it released reduced temperatures in some distant parts of the world so much that 1816 has come to be called ‘The Year Without a Summer’. It was an agricultural disaster, and the follow-on effects of the famines had a non-trivial impact on […]

Spells of Ecological Succession

Nature is never static. Land that was one ecosystem this century may be another next century – or even next year. Every acre is, ecologically speaking, always coming from somewhere and going to somewhere. So let’s use this principle of ecological succession to devise some cool spells! Flesh to Stone and Earth to Mud are […]
