Side-Trek adventure When your PCs gain access to the teleport spell, their whole world changes. That simple spell opens up instantaneous, long-distance travel. No more long overland journeys or dangerous retreats through hostile territory. All it takes is clasped hands and a word from the wizard, and poof! The PCs are where they want to go. Except that it isn’t that simple, because teleport isn’t foolproof. The off-target teleports are a matter of scattering your PCs someplace else on the map and forcing them to get their bearings and make the long overland journey anyway. But this Side Trek focuses on the really intriguing column on the teleport chart: “similar area.”

Listen up! You're in my dungeon now, Morty! On Earth C-141, I'm a LEGENDARY D&D adventure writer! When people think of impossibly difficult dungeons or winding, labyrinthine maps, those things ain't Gygaxian - they're SANCHEZIAN! I do whatever I want over there, and they eat it up! I'm a celebrity Dungeon Master there, too! My livestreamed show, Cynical Troll, gets a billion views a day! It seemed a little selfish to contain all that GREATNESS to a single dimension, so I lifted one of the all-time favorite Sanchezian adventures and snuck it back here to dimension C-132. (Usually that kind of s**t is frowned upon, but it's just a D&D adventure. We're not exactly violating the Prime Directive or whatever.) This is a good old-fashioned dungeon crawl for a party of 1st-level adventurers, whose character sheets in this box should also contain. They'll probably reach 3rd level by the end of it. So here it is. This adventure brought peace to a warring galaxy. What did you ever do? Oh, you picked up this adventure? Good start. And awaaaay we go!

Stories of misfortune are often exaggerated, especially when they have been retold many times. For that reason, most people aren't taking seriously the claim that a sea monster living along the coast is eating whole ships full of sailors and swallowing entire families. But there's no denying a few facts -- the town of Lochfell is losing its citizens to a sea monster (one that walks on water no less), someone is stealing that same town's dead, and ships are beginning to choose other ports for unloading their goods. Such a scenario could doom the residents of the small port town to either a monster's gullet or the poorhouse. No one seems to know whether the town's two ongoing problems are connected, but the sea monster never leaves behind a corpse to bury. Is it collecting bodies for some dark purpose? Or did some more powerful evil creature create the sea monster to do its dirty work? Someone in Lochfell knows the answer, and it's up to the PCs to find it out. Lochfell’s Secret is a short D&D adventure for four 15th level player characters (PCs). The story is set in and around the port town of Lochfell. You can place the action in any section of your campaign world where a coastal town on a bay might exist. If there is a small town that the PCs visited in a past adventure but haven’t returned to in quite a while, so much the better. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.

Into the Forsaken Temple's Crypt is a short adventure for four 10th-level characters. The adventure takes place in a buried temple crypt, which has been sealed for centuries.

Now they face the very golems that killed a drow cleric.

In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers.

Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately. About three years ago, a medusa, Zhanna Serpentlock, began systematically turning every person in Duke Jellhyn Fedorel's (N male human Ari5) duchy to stone. After losing many peasants to the medusa, Jellhyn attempted to placate her. He offered her his second son, Dephyl, for a husband. Duke Jellhyn and his family had always been rather tense and uncomfortable around Dephyl anyway due to the fact that Dephyl had lost an eye in a freak magical explosion as a boy. Zhanna accepted the marriage, and though Dephyl didn't really care for his family due to how they treated him, he was also less than happy with the arrangement. A year ago, Zhanna appeared at Fedorel's citadel again. She claimed that Dephyl had been untrue and that she had turned him to stone for his adultery. Throwing Dephyl's stone head down in the courtyard of the citadel, she swore vengeance on all Fedorels for his betrayal. Duke Fedorel and his household fled the citadel. Rather than give chase, Zhanna took up residence there and began ruling the duchy as the sole remaining Fedorel family member. Jellhyn and his family have lived in exile for a year. This is what the PCs can learn, but more is going on. As it turns out, Dephyl is alive and quite happy with his marriage. Zhanna is not repulsed by his disfigurement as his family was, and Dephyl's missing eye is something of an asset in the relationship since it lessens his chance of being accidentally petrified by his wife. In the two years of his marriage, he has grown up and gained ambition -- he wants to rule. As a second son (pawned off on a monster), he would never have received the chance. Now, with Zhanna's help, he can rule. However, Dephyl doesn't have the stomach for killing his father and brother. Instead, he and Zhanna plotted to take over the duchy by frightening everyone away. Zhanna carved a stone bust of Dephyl and used it to frighten off the rest of his family. Now Dephyl and Zhanna live happily in the citadel and rule the duchy together, though Dephyl's existence among the living is a secret.
