Long ago, a small but mighty humanoid kingdom existed in what is now the local wilderness. Bugbear and ogre warriors fought brutal wars of expansion, earning great fame and amassing considerable fortunes from their predations. Those who died in battle were buried in large tomb complexes dug into hillsides and honored as patrons of the living. Among these tombs was the large tor known as Hightower. Though it was neither the largest nor the most famous of the kingdom's tombs, Hightower did represent a typical example of this kind of structure. As happens to all such nations, the cruel humanoid kingdom eventually fell to a more powerful foe that razed all its cities and outlying fortifications. Of the tombs, only Hightower escaped destruction -- largely because it was an unimportant monument in a remote location. A few tribes of humanoids that survived the devastation tried to use it as a fortress, but the humans with whom they clashed defeated them soundly and sealed the entrance with a huge, round stone to ensure that the tor could no longer be used as a base. Since then, Hightower has served as a landmark for travellers in the know, but it has otherwise been largely forgotten. But the electrical storms that have plagued the area in recent days have been quite severe, and a few weeks ago, a stray lightning bolt broke open the stone seal. Tonight, yet another terrible storm is sweeping through the wilderness, driving all creatures to take shelter where they can find it. Hightower looms on the horizon, and its door is no longer blocked. Will the PCs dare to enter its silent halls?

Long ago, before the arrival of civilized humanoids, a large colony of ogres thrived in the local area. When a great invasion from another dimension threatened this colony, their king, Koptila, prayed for his people to be spared. The gods heard these pleas, but commanded Koptila to sacrifice himself. The leader did so, and the clan disappeared—whisked away by the gods and lost to time. Over the years, a city grew up above the former subterranean home of the ogres, and no aspect of Koptila’s ancient bargain was preserved or remembered. Even so, the stars are aligned for the return of Koptila and his people. These powerful repatriates are unlikely to appreciate the changes in their old home. A sage has found dusty documents prophesying this return, and he asks the PCs to investigate the catacombs to defeat the potential threat to the city.

On the southern shores of the Moonsea, the residents of Mulmaster have eked out a living where others would likely have given up long ago—in a bleak city where corruption is rampant and the Church of Bane holds sway. In these five short, introductory adventures, you will travel the breadth of the City of Danger, meet its people, see its sights, and witness firsthand how the city truly has earned its ominous moniker. An introductory adventure for 1st-2nd level characters. City of Danger is broken into five mini-adventures, each designed for one to two hours of play. Therefore if you are attempting to run all five missions in one session you need a minimum of five hours to do so (and probably more). If running this adventure as part of an event that cycles players through quickly, the DM should be familiar with the mini-adventures that he or she is going to run. At public events, time is often the most important factor. Get the players into the mini adventure as quickly as possible, keep an eye on the clock, and take whatever shortcuts are necessary to stay on schedule. If time is not an issue, let the characters spend more time interacting with the non player characters within the mini-adventures. It is not required that the mission be played in order.

Though small, Seawell is a prosperous trading town with a good location on the coast. Next to it is a long peninsula that features mostly swamplike terrain. The inhabitants of this peninsula include tribes of lizardfolk, plus several kinds of reptiles and amphibians. Most of these creatures don't bother the town, and Seawell's militia is experienced at repulsing raids by the more aggressive lizardfolk. A large reef extends the entire length of the peninsula on the side away from Seawell. This great wall of coral is a favorite site for fishermen, but it has always presented a serious hazard to ships approaching from that direction. Thus, about 45 years ago, the people of Seawell built a lighthouse on a small promontory near the reef, about 200 yards from the shoreline. Operated by a family that lived inside it, this lighthouse ensured that ships could easily steer clear of the reef. A few weeks ago, ships stopped arriving from that direction. Three ships are now overdue, and the people of Seawell have begun to suspect foul play. Thus far, however, they have not been able to investigate because of increased raiding by the lizardfolk. Something has stirred them up, and the town militia has been too busy repulsing raids to mount an expedition to the reef. Wreck Ashore is a short D&D adventure for four 1st level player characters (PCs). The scenario takes place on and around a swampy peninsula that juts out from a longer stretch of coastline. Along one side of this peninsula stretches a dangerous reef. Just offshore on the reef side stands a lighthouse built to warn ships of the danger. At the base of the peninsula on the side away from the reef is a small port town called Seawell.
