From time immemorial, the rulers of the mortal world have been counseled and tempted by capricious primordial spirits who rule over the elements. The greatest and most sinister of these was a half-kraken medusa known as the Maelstrom Queen, who sought to supplant the mortal races with her own line of immortal tentacled monstrosities. On the verge of her ultimate triumph, when the leviathans at her command rose from the depths, a legendary assassin murdered the Maelstrom Queen in her half-submerged palace with her own weapon. But the primordial mistress refused to let something as trifling as death put an end to her designs. Every 13 years, she regenerates enough mystic power to rise again, and the world’s greatest heroes are sent to murder the Maelstrom Queen once more.

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.

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.
