Designed for a party of five characters of at least 9th level, this adventure will challenge players seeking a powerful magic item of the GM’s choosing. A sphere of annihilation has been provided and is woven into several elements of the adventure, but any appropriately powerful item can be substituted if something else suits your campaign better. Though the adventure is designed to test every type of character class, a rogue who can deal with traps is essential, as is a wizard or sorcerer of at least 9th level. Larger groups will have an easier time; parties of four or fewer characters will be in for a very bad time unless you mitigate some of the tower’s more lethal traps and encounters. This adventure culminates in an encounter with devils and a sphere of annihilation. The sphere of annihilation is hidden deep within the tower-and-dungeon complex of Crane the Sorcerer. Originally set atop a high mountain in a secluded and wild part of the world, the tower and dungeon can be relocated to meet the situation in your campign. Crane, an introvert, stayed as far away from civilization as possible, as is detailed below. The tower above the dungeon doesn’t present many difficulties for a group of powerful characters or alert players. It might lull PCs into a false sense of security before they enter the areas where they’ll really be put to the test.

Eternally does the Lord of Nessus scheme, and his designs are for all eternity; In the pit of Hell do the devils teem round his throne, and his reign is unchallenged; By the eight Dark Ones is he held supreme, and his name (speak it not!) is Asmodeus. - From "The Canticle of Thumis," 142:15 To some, justice is more important than glory, duty is more important than desire, and goodness is more important than life. The great paladin Klysandral was such a man. But even the sleep of death, at the end of a long lifetime spent battling evil, did not bring peace to Klysandral. During his funeral, the entire Temple of Neheod was dragged by terrible magic into the Nine Hells, along with the soul of Klysandral and scores of living mourners! What unearthly motive could be behind this tragedy? Only the bravest, strongest, and most resolute heroes will have the mettle to find the answer. Along the way, they will meet the enigmatic wizard Emirikil the Chaotic, sail aboard the fiendish ship Demonwing, and finally face the horrific minions and overwhelming terrors of Hell itself. Only the path of light can lead the bravest of the brave into perdition and safely out again. Step wisely, and walk in justice.
