A cold winter wind blows from the Scourge Mountains, but its origins are not of this world. And with it come horrifying stories of a fey who walks the land. Cold, beautiful, and deadly, she turns every mortal she touches into a statue of ice, and she seems determined to blanket the entire north in a blanket of frost.

Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home.

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.

A sickness has come unto the simple mining community of Duvik’s Pass, poisoning their wells and blighting their crops. With the pestilence leaving the strongest men of the town’s guard a few short days away from death, the burden of descending into the mines and purging the wellspring of whatever evil has settled there falls to an intrepid band of adventurers. Can these noble heroes prevail within the depths of Duvik’s Pass, or will they too fall victim to the perils of The Burning Plague? The Burning Plague is a DUNGEONS & DRAGONS adventure designed for a party of four to six characters of 1st level. Dungeon Masters (DMs) should feel free to adjust the adventure as necessary to accommodate groups not falling within this range. However, given the fairly low power level of the inhabitants of the mines at Duvik’s Pass, it should be noted that parties consisting of 20 or more total levels are unlikely to find satisfactory challenge within The Burning Plague.
