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

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.

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.

Beyond the mortal world, somewhere outside the bounds of the Astral Sea, the Far Realm yawns immeasurable. Beyond the reality of gods and mortals, this plane is a realm of contradictions, a mad place of fevered creation checked only by pointless extinction.
