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

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...

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...

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...

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.

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.

An icky sideline plot to a forest adventure.
