Random Adventure Generator

Theme	Action/Adventure
	This is the most common and straightforward sort of adventure there is. In the Action/Adventure scenario, you present your characters with a task and then confront them with obstacles to overcome in order to accomplish the task successfully.
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	Chase to Ground
	First, you have the Heroes Chasing the Villain. The villain, after a series of encounters with the heroes, is running to safety, to some place where he can acquire more power, or to somehwere he can accomplish some dread purpose such as assassination or mass murder. The heroes chase him, have to deal with the obstacles he leaves behind, and finally catch up to him before or just as he reaches his goal. Here, we have the final duel between the villains forces and the heroes. Second, you have the Villain Chasing the Heroes. Often, in a story like this, the heroes have found out how to defeat the villain -- such as getting to a particular temple and conducting a particular ritual. The villain chases them all through their quest, catching up to them just as they're commenciing their ritual; they must, with heroic effort, conclude the ritual while suffering his attacks. Third, you have the Master Villain's Sudden Escape Attempt. This takes place in adventures where the Master Villain's identity is unknown until the end. His identity is revealed and he makes a sudden bolt for freedom; the heroes give chase. This usually results in a dangerous foot-chase through nasty terrain -- such as across rooftops, through the dungeons, or across an active battlefield.
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	Palace of the King
	The heroes could be here for many, many different reasons: Trying to get a favor from the ruler, part of some nobleman's retinue, members of the palace guard, sneaking in to save the ruler from assassins, sneaking in to assassinate the ruler, thrown into the dungeon for crimes they did or didn't commit, etc.
Specific Setting II	Caves of Magical Folk
	These can be either beautiful, glittering homes of gorgeous magical peoples, or the dank and terrifying lairs of horrible monsters.
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	Inquisitor
	This villain is the one who interrogates the heroes and NPCs captured by the villains. He accompanies the other Minor Villain out into the field and works on anyone captured; he enjoys inflicting pain and suffering.
Minor Villain II	Inquisitor
	This villain is the one who interrogates the heroes and NPCs captured by the villains. He accompanies the other Minor Villain out into the field and works on anyone captured; he enjoys inflicting pain and suffering.
Ally/Neutral	Talkative Barkeep
	This classic encounter is the garrulous innkeeper who has information the characters want; trouble is, they'll have to bribe him to get it, or agree to stay at his inn, or buy a lavish meal, or listen to his incessant stories about his career in the army, or whatever.
Monster Encounter	Reconaissance Monster
	At some point in the adventure, the Master Villain will become aware of the heroes' activities against him. If he has magical abilities or a magical servant, he will send some sort of quiet, clever monster to spy on the heroes. The heroes should have an opportunity to realize they're being spied upon, leading them to a mad scrable as they try to capture or destroy the spy.
Character Encounter	Lying Accuser
	A captured thief may accuse the character of putting him up to the theft; an abandoned mother may accuse the hero of fathering the child; a reputable witness (working for the Master Villain) may accuse the hero of a murder or robbery. The hero shouldn't know what he's accused of until he's hauled in by the authorities.
Deathtrap	Demolition Zone
	In this classic deathtrap, the heroes are placed (usually bound and weaponless) in some building or area just as it's due to be destroyed.
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	Hero Fulfills Prophecy
	This is the most useful sort of prophecy. In the early part of the adventure, one of the heroes discovers that he fulfills some ancient prophecy.
Secret Weakness	Element
	The Master Villain can be banished, dispelled, killed, or otherwise defeated by some of element or item. The Master Villain tries to get rid of all the examples of this element in his vicinity; he doesn't let his minions carry it or bring it into his presence. But he's not stupid; he doesn't announce to the world what his weakness is. He tries to hide his concern within another command. If he's allergic to red roses, for instance, he orders all "things of beauty" destroyed within miles of his abode.
Special Condition	No 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 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	Lying Rumor
	This is the worst and most useful type of red herring -- the interesting rumor which just happens to be false. In adventures of this sort, the best Lying Rumor concerns the Master Villain; it gives the heroes some "important" information about him which later turns out to be useless.
Cruel Trick	Heroes Must Work with Villain
	If they have to work for the villain, it's due to some hold he has over them -- probably, he's kidnapped one of their NPCs and will kill this person if his demands aren't met. Put the heroes through the encounter where they have to do something they are loathe to do, such as sack and pillage a temple, before they have the opportunity to retrieve their friend.
