Random Adventure Generator

ThemeEspionage
Espionage adventures are active, grim scenarios involving spying and perhaps other cloak-and-dagger deeds such as assassination or rescue.
GoalExplore a New Area
The heroes are hired or convinced to enter an unmapped area and explore it. They may be making a map; they may be trying to find someone who disappeared into this area in the past; they may be following legends that tell of treasure in the unexplored interior.
Story HookLegend and Rumor
In this classic story hook, the hero stumbles across some new or long-forgotten knowledge that promises great treasure or gain.
PlotA-B-C Quest
This is an epic sort of plot. In it, the heros are given (or undertake) a task to perform: The taking of a city, the rescue of an innocent, the destruction of a monster, the creation of a magical item, the defeat of a Master Villain, etc. But the path to victory is not a simple one. To get to their goal, Event A, they find that they must first accomplish some other task -- Event B. But when they undertake the task of accomplishing Event B, they find that they must first accomplish Event C. This goes on for several encounters, until the heroes accomplish all the obstacle events which prevent them from returning to Event A, their original goal.
ClimaxThrone Room Duel
This is set up much like the Scattered Duels, except that you don't separate the heroes. It's harder to control whom fights who in this situation... but if it doesn't matter who has the final duel with the Master Villain, this is a classic climax choice.
General SettingExotic Distant Land
The adventure will take the heroes to some fascinating and exotic distant country, where they'll have to cope with new customs, monsters unfamiliar to them, and very colorful NPC encounters; choose one of the more fascinating foreign lands from your campaign world.
Specific Setting ITavern/Inn
This is a classic fantasy setting, the residence of travelling heroes and the home of the tavern brawl.
Specific Setting IITemple/Church
This can be either the church of some lofty and good diety, or the dark and grisly temple of some horrid deity (doubtless filled with evil soldiers and monsters), or even the temple that the madman villain has dedicated to himself for when he becomes a god.
Master VillainCorruptor
The Corruptor is the villain who wants to make something nasty out of something that is currently nice. He may be working on a small scale -- i.e., wish to corrupt one character or a few characters, particularly PCs and their favorite NPCs. Alternatively, he may be a big-scale villain trying to change an entire city or nation into a jaded, debased pit of sin, hatred and death.
Minor Villain IMoronic Muscleman
This fellow is a huge, powerful monster of a fighter. His job is to smash anything the villain tells him to smash. He does that very well, but don't ask him to do any thinking; he has no time for such brainy stuff.
Minor Villain IIMistress with a Heart of Gold
This character is much like the "Lover or Daughter of Villain" type of Mystery Woman from the Story Hooks section. In this case, she usually accompanies the Master Villain, but sometimes goes on missions of her own, where she runs into and develops affection for one of the player-characters.
Ally/NeutralGovernment Observer
For some reason, the heroes' ruler wants one of his own people accompanying them. Whatever the reason, the heroes are now stuck with a haughty, self-important royal observer, an expert in (probably) military tactics or espionage. He continually offers unwanted advice and tends to get the heroes into trouble by pulling rank whenever he's not satisfied.
Monster EncounterNocturnal Predator
This is a classic monster encounter; the arrival of a hungry carnivore in the middle of the night. Usually, this attack happens to heroes camping between villages or out in the deep wilderness; a wild animal, attracted by food odors (from the heroes' campfire or from the heroes themselves) sneaks in for a bite.
Character EncounterThief
At some point in their adventure, the heroes have a run-in with thieves.
DeathtrapFramed
One or more of the heroes is accused and convicted of a capital crime -- one for which the mandatory punishment is death. The heroes must escape or die, and they're escaping from the well-built, well-protected prison of the local authorities.
ChaseAerial
The heroes could be riding pegasi or friendly griffons or allied great eagles; the villains could be carried aloft by gargoyles or demons. The prospect of taking a mile-long fall if one's mount is hit is a very daunting and challenging one for the hero.
Omen/ProphesyReincarnation
The hero, seeing the portrait of some long-dead nobleman, may be surprised to see his own face staring back at him. All evidence points to the fact that our hero is the reincarnation of this person, and the Master Villain may desire to destroy any trace of that nobleman's existence. Just as appropriately, this long-dead nobleman may have died after making some important choice -- such as choosing love over career or career over friends; and the choice he faced is identical to the one the hero now faces. Will our hero defy the prophecy and choose as he did in a previous life, or will he choose the other option and see what happens?
Secret WeaknessHoly Symbol
The villain may have the traditional weakness to a specific holy symbol -- but don't choose just an ordinary one. It may be a holly symbol no longer used by the church, or may be some forgotten variation of the current symbol. (For instance, the cross may not work, but a variation -- such as the Roman cross -- might; alternatively, it might have to be a holy symbol which has undergone some unfamiliar ritual.)
Special ConditionNo Lawbreaking
For some reason, at one point in the story, the heroes cannot allow themselves to break the law -- even when it would help them greatly to do so. For instance, the heroes may be asking for the help of a king whose word is law and whose power is immense. When they arrive for their audience, an emissary of the Master Villain is making a similar plea for help. If the heroes attack and kill that emissary, they will lose any chance at the king's help -- in fact, he may order their execution.
Moral QuandrySaving Quandry
Finally, another classic quandry puts the heroes in the position of choosing between a grand opportunity to hurt the Master Villain -- or saving the lives of a number of individuals.
Red HerringFalse Path to the Artifact
Once again, if the heroes have had too easy a time finding the artifact capable of destroying the villain, give them trouble this way: When they get to the place where the artifact is supposed to be contained, they find the coffer or chamber or whatever empty, obviously looted by robbers, who have scrawled such remarks as "Kelrog was here!" upon the walls.
Cruel TrickNPC Turns Traitor
He may alert he enemy when the heroes are planning a raid; he may steal the artifact and take it to the villain; he may stab a hero or important NPC in the back (literally) before departing.
