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.

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

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.

"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."

An impressive citadel in the Askharnn mountains. Their prohibitive laws on travel during the Winter months can be a problem for pilgrims and wanderers.

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...

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...

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...

The grisly anthropomorphisation of a rockfall...

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.

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.

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.

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...

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...

An icky sideline plot to a forest adventure.

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

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.
