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

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 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.

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

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.

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.

A dangerous book of maps...

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.
