Centuries ago, a green dragon terrorized the civilized lands near its lair. As the beast grew in power, countless cult followers gathered. With the help of its worshipers, the dragon transformed into a runescribed dracolich. The dragon and its cult grew larger and more powerful over the centuries. This, of course, led to war with the surrounding nations. After terrible battles and much loss, the cultists were slaughtered and the dragon destroyed, but its phylactery could not be found. The beast reformed, gathered cultists anew, and again was defeated. The phylactery still could not be found. This time, the powers of civilization decided not to destroy the beast, but to trap it, locking it away and setting various guards. Recently, a divination ritual performed by someone the PCs respect revealed that great peril will arise if a creature lairing in Mount Sorrowspire (the dracolich) is not destroyed. Pgs. 180-185

It's a frigid New Year's Eve, and the heroes gather near midnight in a small condemned tavern wihtin the Free City-State of Gate Pass. Located in the mountain pass which separates two hostile nations. Gate Pass has been neutral since the end of their last war. That neutrality is about to be put to the test, as a scourge comes for the city from the nearby empire of Ragesia. By now, every magic-user in Gate Pass knows of the Scourge. The Emperor of Ragesia died barely a month ago, and a witch named Leska has moved to cementer herself as the next empress. Leska leads the Ragesian Inquisitors, clerics specialized in countermagic and has decreed ass disloyal mages to be tracked down and killed to prevent future threats to the empire. Their first target is Gate Pass, whose neutrality has long been viewed as an insult to the nation's honor.

A ten-part, fourthcore megadungeon designed to take a party of 4-6 players from level 1 to level 10. The Voice of All spoke three times before falling into silence. The first time to give shape to the Ancients. The second to give them the world as their domain. The third to build the TOWER for the war that was to come. And war did come. The Ancients, primordial warriors charged with protecting the world, were subverted by three great crusaders, vindictive and powerful. The Ancients were stripped of immortality and cast from the heavens to serve and suffer with the rest of humanity. The crusaders claimed new bodies for themselves, and became the Triumvirate, god-tyrants of all realms. The long line of descendants of the Ancients is dwindling, along with humanity’s last hope. What few remain have gathered to enter the TOWER OF THE ASCENDANTS. Crumbling stone tablets of ages forgotten say that a mortal who ascends the TOWER that pierces the heavens and slays the gods who dwell in its highest bower will reclaim lost immortality.

He madly believes that he can stand against the Raven Queen, and seeks allies of all stripes—even her own servants—to do so.

Beneath a decayed keep, the undead dragonborn has reopened this portal and led his forces into the Shadowfell itself. The PCs are called in to beard the death knight in his lair.

Your PCs are reaching the upper end of the heroic tier. New worlds are opening up to them—they might have already ventured to the Feywild, for example, and made contacts with inhabitants of that magical plane. Now they are ready to take their first steps into the darkness. The Shadowfell awaits... Vandariel, a shadar-kai witch who calls herself the Voice of Pain, is a fanatic devotee of the Raven Queen. She has founded and become the self-proclaimed high priest of a bizarre cult, the Lords of Pain, whose purpose is to bring more fey into the shadow pact with that goddess of death. Although the original shadar-kai entered this pact voluntarily, and the race breeds true, Vandariel is consumed by what she sees as a divine mission to reveal the mystery to all fey—whether they wish it or not. Those who do not come voluntarily to the truth are brought against their will. Dark stalkers move like the night, seeking out and abducting suitable subjects. This Side Trek can serve as an introduction to the dangers of the shadow realm. It works well for PCs who are approaching the paragon tier, since it presents a reasonable challenge for characters of 10th level. It is suitable as a climactic encounter for lowerlevel adventurers, as well. It consists of only two encounters.
