Random Adventure Generator

Theme	Horror
	This type of adventure is designed to scare both the characters and the players. Just having a monster attack is not enough for a horror theme; the monster must first frighten the characters.
Goal	Thwart Monstrous Plan
	This is a classic fantasy-adventure plot: The characters learn of some horrible plan made by a monstrous enemy, and must thwart it before the kingdom is lost or the world is destroyed. This is an epic goal, and usually requires that the characters go to all sorts of places, rounding up allies and artifacts, before being strong enough to face their enemy.
Story Hook	Dying Delivery
	On some occassion when the hero is out wandering the streets or is otherwise all alone, a dying man bumbs into him, hands him something, says a few words, and dies.
Plot	Accumulation of Elements
	In this sort of plot, the heroes have to go from place to place -- perhaps covering very little area like a city, perhaps roaming the known world -- and accumulate elements to be used against the Master Villain. These elements may be clues, pieces of an artifact, evidence, or allies.
Climax	Prevented Deed
	Here, the heroes have been defeated -- captured by the Master Villain, or so thoroughly cut up by his minions that all believe them to be dead. And the heroes have learned, from the bragging of the villain, loose talk of his minions, or examination of clues, what is the crucial event of his master plan. In any case, the battered and bruised heroes must race to this site and have their final confrontation with the villain, bursting in on him and his minions just as the knife or final word or key is poised, and prevent the awful deed from taking place -- and, incidentally, defeat the master villain and minions who beat them previously.
General Setting	Exotic 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 I	Classic Dungeon
	This would be the standard monster-filled labyrinth; perhaps it's a nesting ground for the master villain's monster troops.
Specific Setting II	Classic Dungeon
	This would be the standard monster-filled labyrinth; perhaps it's a nesting ground for the master villain's monster troops.
Master Villain	Conqueror
	This character is moving his army in to take over; that's what he lives for. He's been the enemy of your characters' nation's ruler, and has launched a full-scale invasion of your characters' favorite nation. The heroes have to beat their way through or elude his hordes of soldiers in order to get at him; better yet, they might lead their own nation's troops against his and outthink him in military fashion.
Minor Villain I	Moronic 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 II	Avenger
	This character is much like the Master Villain of the same name, but he's not in charge of all this villainy, and he's definitely an enemy of one of the player-characters. You'll have to decide who he is and why he hates one of the heroes; he could be anything from a recurring villain to someone who simply lost a fight to the hero once.
Ally/Neutral	Romantic Loony
	Somewhere, the heroes bump into a lunatic who falls immediately in love with a player-character and won't leave him or her alone. This character may be a love-smitten village lass or nebbishy adventurer. Whatever the origin, this character must be hopelessly in love with the character but have some trait which keeps the character from reciprocating; perhaps the loony is too plain, too crazed, or too stupid. Whatever, he or she really is sincere in his affection for the character.
Monster Encounter	Loving Deceiver
	One of the player-characters, specifically one of the better-looking ones, attracts the attentions of a very attractive local of the opposite sex. This local person, encountered in unthreatening surroundings, invites the hero off to a liason away from his friends and other people. Of course, this person is a human-appearing monster of some sort; once alone with the character, he/she will attack the character with monstrous intent.
Character Encounter	Truthful Accuser
	This encounter is like the Lying Accuser except that the accuser is telling the truth. Dig through your characters' pasts, uncover a misdeed or two, and, when the heroes are at a critical point in their adventure, confront them with someone they actually have wronged. This person has found them and appealed to sympathetic local authorities. The heroes will have to make good or have the authorities on their backs for some time to come.
Deathtrap	Tomb Deathtraps
	Another classic type of trap is the sort of triggered trap left behind in abandoned tombs, ruins, and catacombs. Here, a hero who touches the wrong step, floor tile, wall brick, torch bracket, mounted gemstone, or other device will trigger some sort of ancient trap designed to kill tomb-robbers and intruders.
Chase	Special Terrain
	You can make any chase more memorable by having it take place in a setting to which it is utterly unsuited. For instance, horse chases are fine and dramatic when they take place through the forest, out in the open plains, or along a road -- but they become diabolical when they take place inside the Royal Palace or in dangerous, labrynthine, treacherous catacombs.
Omen/Prophesy	Birthmark
	One of the heroes has a birthmark that pertains to the adventure in some way. He may have a birthmark identical to some NPC -- for instance, some person endangered by the Master Villain. This mystery can give the hero his reason to become involved. Alternatively, his birthmark may mark him as a hero fulfilling some ancient prophecy.
Secret Weakness	Secret Embarrassment
	Finally, the villain may have some aberration or secret shame that will force him to flee when he is confronted with it. It could be something as simple as the fact that his nose is too big, or that he is a small and nebbishly wizard pretending to be some vast, powerful demonic power. When his shame is revealed, he is too humiliated to continue; this is a good option for comedy adventures.
Special Condition	Stolen Identities
	This option requires that the Master Villain be of godlike power oor possess some sort of artifact. Once the Master Villain realizes that the heroes are on his tail, he uses his powers or artifact and steals the heroes' identities. One day they wake up -- and no one knows who they are. They retain their memories of themselves and each other, but no one else does. (The villain knows them, though.)
Moral Quandry	Honor Quandry
	You want to use this on the character with the most strongly developed sense of personal honor -- someone who has lived all his life by a strict code. Toward the end of the adventure, this character realizes that the best way to defeat the Master Villain is a violation of that code. For instance, the character might be a paladin, who discovers that the only possible way for the heroes to defeat the Master Villain is to sneak up on him and stab him in the back.
Red Herring	False 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 Trick	Wanted by the Law
	One final complication, one which occurs pretty frequently, is when the heroes are wanted by the law. When they're wanted by the law, they have to travel in secret and very limited in the resources they can acquire.
