In the darkness in the south transept of the Cathedral of Isielles stands the resplendent Clock of Shadows. It tells more than just the time of day...

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...

Sometimes locks need that extra sharp fingernail to twist the catch. Sometimes a thief might find himself locked in a prison with a wooden door. The Muzzled Mouse is a hideous little tool which helps one in such situations...

The characters are stranded on an island, where a wizard, corrupted by the powers of the first Blue Book, has been killed by his own magical experiments. They will discover the awful truth that lurks in his subterranean workshop, and a seed of evil will be sown...

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

A (fairly sketchy) outline of a one-off adventure I ran based around the (time-honoured/hackneyed) Tunguska Event of 1908.

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.

An icky sideline plot to a forest adventure.

I'm trying to think of alternatives for game-openings, to replace the standard 'meet up in a tavern' or 'adventuring group applying for a job' techniques. I know these can be easy ways to get people playing, but I'm certain there are more interesting ways...

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.

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.

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.

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.

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.

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

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.
