Random Adventure Generator

Theme	Espionage
	Espionage adventures are active, grim scenarios involving spying and perhaps other cloak-and-dagger deeds such as assassination or rescue.
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	Pressing Buttons
	As a general story-hook approach, think about the player-character -- his personal goals and his personal dislikes. If the hero is pursuing a specific goal, you have one of the minor villains, as a side-effect of the villain's master plan, thwart the hero's latest step towards that goal. Alternatively, if there's something the hero truly hates to see, have it happen -- and have the villains be responsible.
Plot	Series of Villains
	This is a very dramatic plot, and very well-suited to oriental campaigns. In it, the heroes have undertaken a quest, usually the finding and defeat of the Master Villain. They may have to travel to his citadel, or head off in another direction to find some artifact capable of defeating him, or run away from pursuing villains until they can figure out what's going on. All along their route, they are set upon by villains -- each villain has a name and distinct personality, and each encounter is life-or-death for the heroes and villains; the villain never escapes to safety if the tide turns against him, he fights unto death.
Climax	Scattered Duels
	In this climax, the heroes have gotten to the end of their quest -- they may have broken into, sneaked into, or escaped from imprisonment within the villain's citadel, or have marched into the little town where the villain is holed up -- and they become separated. You can separate them by having traps and tricks break the party apart, by having them see two or three things they must resolve (such as danger to innocents or the appearance of minion villains) pop up simultaneously; they'll have to run in all directions at the same time or suffer failure. Once the party is broken down into bite-sized chunks, you confront each individual or small group with the enemy or enemies he most deserves to face -- his personal enemy, the monster which defeated him before, etc. -- for a grand series of climactic duels.
General Setting	Under the Sea
	This sort of high-fantasy adventure takes place in and under (not on top of) the sea. The heroes require access to some sort of magic item or spell that allows them to breathe water for long stretches, and might adventure in the uncharted depths or perhaps in a community of sea-breathers.
Specific Setting I	Demi-human Community
	In wilderness areas, this will be a large community of demi-humans -- elves, dwarves, halflings, whatever -- or intelligent nonhumans such as orcs. If your action is taking place in a city, this could be a hidden community (such as a secret underground dwarf community) or a section of the city inhabited mostly by demi-humans.
Specific Setting II	Catacombs
	These can be catacombs beneath a living city or a ruined one; they can be long-forgotten or still in use.
Master Villain	Organizer
	This Master Villain is the head of the local criminal syndicate -- the Thieve's Guild or slaver ring, for instance. He's cold-hearted and unsympathetic, and human life means nothing to him. He employs assassins and musclemen against the heroes, and can only be reasoned with when it's going to profit him more to cooperate with the heroes than kill them.
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	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.
Ally/Neutral	Ingenue in Distress
	The heroes must protect some defenseless young innocent who is in danger from the villains. This person, perhaps the sheltered son or daughter of a nobleman or merchant, has no abilities at all but is sweet, charming, and in great need of help.
Monster Encounter	King Beast
	At some point in their adventure, the heroes run across a King Beast -- some enormous, intelligent monster (which speaks the Common tongue) which is the leader of its species. Perhaps it needs help; if the heroes help it they'll earn themselves a favor which the King Beast will repay at some later time in the adventure. Perhaps the heroes are in deadly danger and need help; the King Beast can be persuaded to help, but only in return for a deed or favor in the future.
Character Encounter	Belligerent Soldier
	The billigerent one has just had his ears pinned back by his commanding officer and is anxious to take it out on some hapless civilian. If this is a city gate, he claims that the hero's papers are wrong or that he recognizes the hero from descriptions of a wanted criminal; if this is the streets, he insults the hero's lack of military bearing, pretty looks, clothes, smell, companion, or whatever it takes to provoke a reaction.
Deathtrap	Pit and the Pendulum
	Actually, we're applying this term to any of many time-delay deathtraps. In this sort of trap, the villains capture the heroes and place them in a trap which will soon kill them -- it operates on a delay, often based on a timing device or a burning fuse.
Chase	Aerial
	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/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	Love
	The Master Villain possesses the "weakness" of genuine affection or love -- probably for some NPC, though it could be very intriguing if the object of his affections is a player-character. The heroes can then defeat the villain by holding his loved one hostage, or proving that his loved one will be seriously harmed, betrayed, or killed if the villain keeps up with his activity.
Special Condition	No Weapons Allowed
	At some point in the story, the heroes must surrender their weapons. Perhaps they're visiting some quarter of the city where weapons are not allowed; or a particularly peace-loving temple. In any case, once they're there, they are attacked by enemies belonging to the Master Villain.
Moral Quandry	Respect Quandry
	This is much like the Ally Quandry, only at a greater distance. The heroes have been utilizing the aid of two (or more) powerful NPC allies. Now, in the course of the adventure, the heroes come across a task which can be accomplished in one of two ways -- say, through military intervention or by esoteric magic. The problem is, the NPC allies are arguing for different choices, and the one whom the heores choose against will no longer aid them.
Red Herring	Extraneous Details
	When giving the heroes details on their enemy -- for instance, details they are learning from investigations and readings -- you can give them just a few details too many. This may prompt the heroes to investigate the "extra" (i.e., irrelevant) details in addition to the relevant onces, thus losing them valuable time.
Cruel Trick	NPC 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.
