A dangerous book of maps...

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.

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

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."

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

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.

The grisly anthropomorphisation of a rockfall...

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.

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...

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

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