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...

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.

A disembodied hand enthralled by an evil wizard to fetch books for him.

This looks like an elaborately fashioned wooden egg-cup, but it is a powerful magical tool, used mainly by witches to conjure up spirits and familiars.

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.

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. But then this is an Ideas Guild after all...

Two sly-looking men turn up in town accompanied by a third man who says very little and who they don't allow to be seen much.

"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."

- The Saekeran, book 1 verse 1.

To give a world a feeling of otherworldliness, it is best to replace some standard, everyday objects by imaginitive replacements. I thought I'd turn to musical instruments as music often defines (or embodies) a culture.

This is just a first idea, feel free to post some more, because I will...

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.

The mystery of fyre is one which has much occupyed my studies and the studies of men before me. ... I have concluded that fyre is the product of Fyre Antes.

Professor J Klewlise, "On the nature and origin of fyre" (1542)

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

She has everything: stunningly good looks, sharp brains and oodles of power: she's going to be a Queen. The only drawback is that she doesn't want to be a Queen.

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.

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.

A mysterious quarry. Feel free to suggest explanations - it's just an eerie thought that struck me that I intend to play with.

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

The silver necklaces whose inset gems display the status of the wearer.

A dangerous book of maps...
