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.

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

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...

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

Creepy, Crawley, Buzzing, Digging, Biting, Building, Sticking, Jumping, Clicking, and all the other things these small things do.

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...

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.

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.

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.

An icky sideline plot to a forest adventure.

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

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.

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

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.

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.

(Another submission I'm transferring over to the main site from the fora).
