In the thick, swampy jungles of the south, the oldest and greatest city of Lizardfolk rises majestically over the forest canopy.
This, the largest and most populous city in the world, is a port ruled by thieves, murderers, and crooks.
Some say that Darigus was murdered for his treasure. Others say that Darigus’s court magician did away with the nobleman and ran off with his daughter. And some say that Darigus isn’t dead, and took off with his treasure. But no one knows for sure…
In the burning desert stands a symbol of hope, prosperity, and peace, the place known as Glass Mountain.
Something occured and those in the grand city went mad. Was it a curse, a prophecy, a spell gone wrong, or a magik item opened? Nobody allegedly knows. The city guard on the city walls, saw the madness and were apparently not touched. They tried to keep the crazy ones inside, by blocking the gates and sealing the entrances to the large city wall. The region’s leader, eventually sent the Army there to reinforce the city guards, to hold the mad ones in. Since the mad men are incredibly strong and immune to pain, if they escape it would be a plague upon the land. There is still hope that someday they could be restored (perhaps a royal heir or a royal household was in the city). Perhaps they are nearly immortal. The city guards who occasionally decend into the city to drop supplies and stop fires believe that to be true.
Now it is a small town, with its own walls, that rings the old grand city. Over the years, the army and guards, have created a town that supports them. They think themselves immune to the madness, yet their proximity to them, means they are only slightly odd… perhaps becoming mad. The crazed watch over the mad. A running joke is that someday, someone will man their walls to hold them in.
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.
As long as any can remember, these certain paths allowed one to travel up to and over 20 extra miles a day by using them. One moment one was deep along a small trail, the next he would find himself 20 or more miles farther down the path without realizing it. All was fine until recently. Reports returned talking of the failure of these areas which revealed miles of ancient paths. The protection hiding them has finally failed. Will it release monsters of ages past or reveal magic of unknown worth?
If you want to add a "supernatural" touch to your campaign, define the rules of magic and the universe. Make your players comfortable with those rules. Then your new supernatural creatures must then break those rules.
