In the Yatil Mountains south of Perrenland there is rumored to be a magical hoard of unsurpassed value, a treasure of such fame that scores of adventurers have perished in search of it. Find the perilous Lost Caverns of Tsojanth and you may gain the hidden wealth of the long-dead arch-mage-- if you live.

The Grand Duchy of Geoff has recently been plagued by a rash of unusually weird and terrible monsters of an unknown sort. This western area, particularly the mountain fastness which separates the Grand Duchy from the Dry Steppes, has long been renowned for the generation of the most fearsome beasts, and it has been shunned accordingly -- save a handful of hardy souls with exceptional abilities. Within the last few months, however, a walled town not far distant from the area, and four small fortresses as well, have been destroyed by mysterious attacks! This classic adventure set on a crashed spaceship challenges the players assumptions, and expands on what's possible within the "fantasy" label. TSR 9033

The coastal city of Magnimar is no stranger to crime, yet recently, a series of murders has sent a chill through the early morning streets.

None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.
