ThemeAction/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.
GoalThwart 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 HookOld Enemy
This is a straightforward story hook; the hero learns that his oldest enemy is back and is very active in the campaign, up to something. The hero will naturally want to investigate and will walk right into the story.
PlotSeries 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.
ClimaxPrevented 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 SettingOn the Sea
Most of the action occurs on the sea -- the heroes are shipborne for some reason, docking in lots of ports. Again, this is good for adventures where the heroes are investigating clues left all over the map, are part of some trading enterprise, or are being pursued by villains.
Specific Setting IMilitary Encampment
This is best used in an episode involving warfare; it could be the good-guy army's encampment, from which the heroes launch their adventures, or the villains' encampment, in which case the heroes might have to sneak in on a mission or escape from it if they're captured.

Master VillainAvenger
This villain seeks to avenge some wrong he thinks he's suffered. He may be right; he may have suffered a wrong, and this makes him a little more sympathetic than villains who are purely evil. The Avenger uses his organization -- thugs and bribed officials -- to get at the one who wronged him, and will want either to duel (singly) the one who wronged him, or to put the wrongdoer in a deathtrap.
Minor Villain IChildhood Friend with a Dark Secret
This Minor Villain is like the character of the same name from the Allies and Neutrals section. However, the heroes find out early on that he's really working for the Master Villain. He may not wish to be helping the villains; his family may be held hostage, or he may just be too frightened of the villain or otherwise weak-willed to refuse. Alternatively, he could actually be evil now.
Minor Villain IIMisguided Moralist
This fellow has been convinced that only by helping the villain achieve the Master Plan can he improve the world. He tends to be encountered all through the adventure's plot, usually escaping from the heroes and taunting them for their wrong thinking. Fortunately, he's no more effective as a villain than he is as a thinker.
Ally/NeutralGibbering Madman
Some poor wretch blundered into part of the master villain's plan and saw too much. What he saw drove him crazy. He gibber and jabbers, occassionally uttering clues about what he's seen, but just isn't coherent. He knows enough that the heroes will need to take him along to comment on what they're encountering, though, so he can't just be met and forgotten.
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 EncounterPress 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.
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.
ChaseFootrace
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/ProphesyBirthmark
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 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 ConditionMagic Doesn't Work Right
If the adventure is taking place on an alternate plane, then that plane's magic works oddly or not at all. (A spellcaster will find that just making himself useful is a challenge when none of his spells works.)
Moral QuandryFriend Quandry
At a critical point in the story, one of the campaign's NPCs makes an impossible demand of one of the heroes.
Red HerringLying 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 TrickVillain is Related to Hero
In this very irritating complication, one of the heroes discovers that the Master Villain is related to him. The villain might be his long-lost father or twin; perhaps this relative is not long-lost after all, but has secretly been a Master Villain for years, and only now has the hero discovered it.
