The Despotic Queen of Shiant has decreed that a competition will take place in the month of Oconerry. She will have built a labyrinth through which the contenders must pass in order to win the ultimate prize: her hand in marriage.

The Great Gate of Calast is not like other gates. It's got a mind of its own...

Although it can be a distraction, it can also add atmosphere to an adventure to have music playing in the background. Here are some pieces I'd recommend for different situations.

"When our barbarian ancestors first arrived on the plains of our homeland, they found them covered in dust inches thick. They named them Muranvan, the Dusty Plains and armed with spades they cleared the dust heaving it off the edge of the world. For they had been chasing the Prey for long aeons up the face of the cliffs at the edge of the world, and in the chase had tired of their nomadic ways. They wanted a stable home. So they founded Takvanak, the City on the Plains. In the long silence after they had cleared the dust from Muranvan, rang out the deep and unforgettable tones of the Iron Heart, Saekeri, and the barbarians knelt and felt resounding reverence."

A dangerous book of maps...

The grisly anthropomorphisation of a rockfall...

A (fairly sketchy) outline of a one-off adventure I ran based around the (time-honoured/hackneyed) Tunguska Event of 1908. As such it is quite specific (hopefully not hackneyed) and will probably best serve as a specimen for dissection to get those parts you can use in your own adventures.

When wizards go mad, what curious ruins do they leave behind?

Unknown to anyone, a glamorous ball for the Duke of Erezi will turn into a confusing and chaotic bloodbath.

Dragons, being huge and meaty, are the ideal habitat for countless unpleasant parasites.

I don't know if I posted about it before, but I have always wanted to run an adventure set in a library. The following is a sketch of an unusual premise and a possible plot-hook.

Language is an essential part of any culture. Culture wouldn't exist without some form of communication, and humans communicate by speaking. But the connection is deeper even than that. The language helps to define the culture which uses it, and is in turn affected by that culture. This dynamic process is what keeps a language 'alive': Latin is a dead language because the culture to which it belonged no longer exists.

Following a discussion we had on the site, I thought we could start up a thread to post the pre- and post-apocalyptic effects of a comet/minor planetary impact on a campaign world.

Carmo keeps a shop in the backstreets of Erezi. It's not often visited, Carmo makes people feel...uneasy. Even the veterans of the Erezi underworld are uncomfortable being alone with Carmo. But they need to buy their traps from somewhere...

(Another submission I'm transferring over to the main site from the fora).

Archaeologists have long wondered about the origins of 'cup and ring-marked stones', the mysterious rocks found on deserted tracts of moorland bearing markings resembling small shallow pits with concentric rings and dating to the Bronze-age.

Hathalfar holds the writhing troll down with his gloved fist and sword. The beast squirms at the touch of metal. 'How far is Kolm?' he demands for the third time. 'I said! A long way away,' replies the troll.

The addition of “irrelevant” details adds local colour to a campaign world, giving the impression that the DM has thought very deeply about the history of even the smallest architectural feature.
