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. It is the Winter of the Witch…and if the archfey Koliada is not stopped, it could be the world’s last. “Winter of the Witch” starts with the PCs receiving an urgent but somewhat cryptic message from the skeletal knight, Sir Keegan.

In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room.

Dare to defy death in this adventure for the world’s greatest roleplaying game. The talk of the streets and taverns has all been about the so-called death curse: a wasting disease afflicting everyone who’s ever been raised from the dead. Victims grow thinner and weaker each day, slowly but steadily sliding toward the death they once denied. When they finally succumb, they can’t be raised—and neither can anyone else, regardless of whether they’ve ever received that miracle in the past. Temples and scholars of divine magic are at a loss to explain a curse that has affected the entire region, and possibly the entire world. The cause is a necromantic artifact called the Soulmonger, which is located somewhere in Chult, a mysterious peninsula far to the south, ringed with mountains and choked with rainforests.

Some of the hamlets outlying Hillsfar have been struck by an odd malady. Rumor has it a traveling carnival visited those hamlets before the disease struck. Does coincidence not equal causation or is something sinister afoot?

Into the Forsaken Temple's Crypt is a short adventure for four 10th-level characters. The adventure takes place in a buried temple crypt, which has been sealed for centuries. Dungeon Masters can adjust it for higher-level characters by expanding the dead magic areas and increasing the number and power of constructs and undead that inhabit the complex. Some things are best left untouched, and some secrets are best left untold. One such secret is the location of the resting place of the traitor Ellowyn Blacktree. Her body has lain undisturbed for centuries, undead but immobile, in the prison the elves created for her. The elven histories tell that Ellowyn was a powerful wizard back in a time beyond human reckoning. While others worked diligently to learn magic, Ellowyn's arcane powers came to her quickly. In her youth, she called this a blessing from Corellon Larethian, and she worked diligently to serve him for the good of all elvenkind. In time, she became one of seven female elves entrusted with the care of a mythal, or elven place of power, devoted to preserving the balance of magic and nature. But Ellowyn, it is said, kept a terrible secret of her own: She had fallen in love with a drow whom history knows as Orith To'rellen. One dark winter night she betrayed her sisters, Corellon, and all of elvenkind by allowing Orith and the followers of Lolth to overrun and defile the mythal. Ellowyn herself was then betrayed by the drow, who abandoned her on the surface near a vampire's lair as they returned to their home in the Underdark, leaving her to face certain death and elven justice alone. In the depths of their grief and anger, the elves sentenced Ellowyn, perhaps unwisely, to dwell forever in the darkness that she had chosen, thus ensuring that she never followed the normal path of life and death that most elves take. Many elves died at her hands before they could restrain her. With terrible spells rarely seen even in that ancient time, they bound her in an underground crypt far away from any living thing. There, the legends say, she waits, nursing a terrible hatred against elves, drow, Corellon, Lolth, and especially Orith To'rellen.

Six months ago, an adventuring group that calls itself the Company of the Shining Stone learned of an aged wizard’s tomb that lay in the rocky foothills of a prominent mountain range, and sought to plunder it. What they were not counting on was that a band of stone giants would move into the immediate area to make their lair. The giants have rebuffed the company’s attempts at getting past them and to their goal. Now is the time of the annual fair in Adurath, a small town located not far from the tomb, and thus, the giants. The giants have no interest in the town or the tomb, but are instead interested in a rare mineral found only in that region. A few of the townsfolk have seen the giants, but there has been no confrontation other than between the giants and the Company of the Shining Stone.

Long ago, a small but mighty humanoid kingdom existed in what is now the local wilderness. Bugbear and ogre warriors fought brutal wars of expansion, earning great fame and amassing considerable fortunes from their predations. Those who died in battle were buried in large tomb complexes dug into hillsides and honored as patrons of the living. Among these tombs was the large tor known as Hightower. Though it was neither the largest nor the most famous of the kingdom's tombs, Hightower did represent a typical example of this kind of structure. As happens to all such nations, the cruel humanoid kingdom eventually fell to a more powerful foe that razed all its cities and outlying fortifications. Of the tombs, only Hightower escaped destruction -- largely because it was an unimportant monument in a remote location. A few tribes of humanoids that survived the devastation tried to use it as a fortress, but the humans with whom they clashed defeated them soundly and sealed the entrance with a huge, round stone to ensure that the tor could no longer be used as a base. Since then, Hightower has served as a landmark for travellers in the know, but it has otherwise been largely forgotten. But the electrical storms that have plagued the area in recent days have been quite severe, and a few weeks ago, a stray lightning bolt broke open the stone seal. Tonight, yet another terrible storm is sweeping through the wilderness, driving all creatures to take shelter where they can find it. Hightower looms on the horizon, and its door is no longer blocked. Will the PCs dare to enter its silent halls?
