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	Rescue NPC(s)
	The characters must rescue one or more kidnapped NPCs, probably from the stronghold of the kidnapper. Obviously, they must get to said stronghold, break in, rescue the kidnappee, break out, and escape back to safety; this usually requires careful and clever planning and a large dose of luck.
Story Hook	Grim Necessity
	If the hero doesn't involve himself with this adventure, he's going to find himself suffering or dead -- period. That's the hook to bring him into the adventure... but you have to determine why he'll suffer or die if he doesn't become involved.
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	Throne 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 Setting	Alternate Plane
	Most of the story takes place in an alternate dimension; this implies that either the PCs or the villains, or both, have magic powerful enough to bridge the dimensional barrier, or that the PCs stumble across some dimensional portal.
Specific Setting I	Madman's Fortress
	This is the citadel of a major enemy: Strong, unassailable, filled with soldiers and monsters, lined with secret passages and deathtraps; not a wholesome place for adventurers to spend their time.
Specific Setting II	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.
Master Villain	Agent Provocateur
	This Master Villain is a clever spy who inflitrates an organization, order, or army, and tries to effect its destruction by getting it to perform actions which will cause others to oppose it directly. The identity of this Master Villain is usually a closely-guarded secret; the heroes will encounter his cover identity, but will not suspect that he's responsible for all this chaos until they start adding up clues. Females in this role can be very, very effective.
Minor Villain I	Single-Minded Soldier
	This most trustworthy of villain minions is the experienced, competent, persistent soldier -- a field-trained officer who serves the villain with military precision. He is usually encountered in the field as leader of the villain's field operations. He is not encountered directly until the middle of or the latter part of the adventure; until then, the heroes encounter only his subordinates.
Minor Villain II	Hard-Eyed Advisor
	This is the sort of villain whom the heroes see in the Master Villain's throne room. He's hard-eyed and scary; life means nothing to him and he enjoys killing. He's also a good advisor to his master.
Ally/Neutral	Merry Minstrel
	This character follows the heroes in order that he might find inspiration for his song and storytelling. He can't be shut up; he sings all the day long and into the night, is a showoff before crowds, and is far too noisy for a party trying to remain unobserved.
Monster Encounter	Noble Beast
	With this encounter, the heroes find that they have to capture -- but not injure -- some sort of powerful, noble beast in order to accomplish their mission. For instance, to reach a mountain-top aerie, they must capture pegasi and ride them up to their enemy.
Character Encounter	Press Gang
	In any port city, the heroes, in a tavern or hostel, may find themselves set upon by ruffians employed by the city; these ruffians use clubs and strike to subdue. If the heroes fight and beat the ruffians, they find themselves wanted by the law for assaulting officers of the peace. And if they fight and lose, they wake up to find themselves sailors, headed far away from their quest! Now they must decide whether they're going to jump ship, mutiny, or just settle down toa few years of seafaring life.
Deathtrap	Mutually Assured Destruction
	In this very nasty deathtrap, the heroes are bound up in such a manner that any one of them may get free of his bonds -- but when he does, all his friends perish. Obviously, the heroes' task is to find some way for everyone to get out alive. Perhaps an intricate series of cooperative rope-cutting will defuse the trap; perhaps a coordinated maneuver will get everyone free as the trap is being sprung.
Chase	Footrace
	The chase involves the characters on foot, probably through such terrain as city streets or the corridors of a palace. One hero may realize that the's being pursued by a party of enemies and choose to run for it; the heroes may have caught up to the Master Villain, prompting him to run for his life.
Omen/Prophesy	Innocent Fulfills Prophecy
	An innocent could fulfill a prophecy -- one which endangers his/her life. This innocent might, for instance, be the one who is supposed to slay the king, but is not a mighty adventurer able to protect himself from the king; the heroes may find themselves sheltering and helping this poor dupe.
Secret Weakness	Holy 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 Condition	Time Limit
	Finally, the most obvious condition to place on an adventure is to give it a time limit. If the Master Villain is going to conclude his evil spell in only three days, and his citadel is three hard days' riding away, then the heroes are going to be on the go all throughout the adventure -- with little time to rest, plan, gather allies, or anything except get to where they're going.
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	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	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.
