Four great and powerful heroes travel in search of adventure. Led by Mordenkainen, wizard without peer, they have come to mysterious Maure Castle, a forlorn and foreboding place, source of wonderment and awesome adventure, following a strange and terrible story. For, somewhere deep beneath Maure Castle, from whence no person has returned alive, there stands two massive iron doors - doors without latch, lock, or handle - the Unopenable Doors. And if the doors are opened, what then? Such potent evil, such terror lies beyond, that even the bravest adventurers may quail before the ultimate test! Mordenkainen's Fantastic Adventure is a challenging adventure for high-level play. Four original characters from Gary Gygax' famous Greyhawk campaign are included for your use. Can you meet the challenge? Can you survive what lies beyond... the Unopenable Doors? TSR 9112

Synopsis: A swamp village is plagued by swarms of insects; several villagers have died from it. It turns out that the local herbalist is actually a vampire who takes the form of a swarm of mosquitoes. Talk to villagers and get rumors, visit the herbalist, suffer through some dreams, get ambushed by the herbalists minions, chase him into the basement to kill him and rescue the villagers. The mosquito vampire and, maybe, the role play involved in convincing the villagers to dig up the graveyard (to find empty coffins filled with sand!) should be fun. The rest of this is pretty simple.

"A dwarven prince has requested your party's aid in quelling the coming invasion (if there is one, of course). Do you take him at his honorable word, and gird yourselves for battle? Or do you listen to the street talk, and take the side of those who disbelieve the warmongering? Most importantly of all: what if you make the wrong choice?" Patriots of Ulek is an adventure set in the world of Greyhawk - designed for a party of six to eight characters of first to third level who must help defend the Principality of Ulek against the despot’s horde and uncover a conspiracy which could lead to Ulek’s defeat.

Thieves will find minimal opportunities to practice their trade, although their skills as spies and scouts may come in handy. This adventure was designed specifically for inexperienced players and beginning dungeon masters. TSR 9385

What happened to the signal tower? What waits for you in the misty mountains? The mayor of the town of Four Trails hires you to find the missing magic user, Delea the White! Delea was tasked with improving the signal tower at Eddistone Point. After leaving with her party of dwarven mercenaries, the mayor received a message from Delea's familiar; a white crow with a note scrawled in charcoal; "Bandits in the tower! Help!" The tower is straightforward, five levels, each a single room. There's a bait-and-switch where the players think the half-orc bandit leader is the bad guy, but an innocuous-seeming vagabond is actually a powerful illusionist. No monsters to speak of, only class-based NPCs, no magic apart from a ring of protection (not listed in this record, being equivalent to magic armor.) Pgs. 19-27

Daggerford is fairly quiet for a frontier town. Sure, lizard men raid the local baron's holding now and then, orcs sneak out of the Misty Forest to raid caravans on the Trade Way, and Lady Bronwyn has a few suitors who are a touch too passionate, but there's nothing going on that a member of the renowned Daggerford militia can't handle. Except that the Shining River has turned green, and cattle are dying. Except that the Elf King of Laughing Hollow, a place where no human dares go without fearing for his life, is asking the militia for help. Except that strange substances are oozing from the fissures caused by a recent earthquake. Except that the earthquake also has opened an entrance in the cliffs around the Laughing Hollow that might lead to the fabled dwarf mines of Illefarn. Suddenly, being a militiaman isn't quite as easy as it used to be. TSR 9212
