My group had to locate the hidden entrance to an abandoned Gnomish city. They searched for two days before they found what they thought was the entrance. It was the entrance…., to Kiddieland, the Gnomish equivalent of a modern funhouse for children. Evil, nasty super-gremlins had infested the place and had warped much of the magic there to terrorize suckers, er, characters who found the way in.
Purple deer have begun to appear near the ruins of a fallen city, or other place of power. Hunting the deer is absurdly easy, as their coloration makes them easy to see. The heros prepare a feast from a freshly killed deer find out several hours later that the meat of the new purple deer is poisonous. This can range from cramps and vomiting to the truly sinister and lethal.
