Four doors of mystery appear in the Cage. They lead to four adventures, if a basher has the dark of them. "These aren't doors in the traditional sense, cutter, but they're portals just the same. They appear for a short time every 500 years, popping up in different parts of Sigil. Each hides a mystery that's waiting to be solved, and together they just might hold the key to a secret of the multiverse. All a body's got to do is tumble to the right keys, open the doors, and face down the Unknown." - Estavan, merchant lord Doors to the Unknown is a collection of four Planescape adventures that can be played separately or as a mini-campaign. When four doors appear in the Cage, the barmies crawl out of the shadows, and the heroes get drawn into events that could have consequences for the entire multiverse. Each door leads to a different plane and a different deadly challenge for the player characters. Together they offer a way to stop an ancient menace before it strikes again.

"Mysterious Ways" is a D&D adventure set in the Holy Land (Israel and Jordan) during the time of the Crusades (1114 A.D.) in an alternate-Earth setting. This is a world where the portals to otherworldly realms, particularly the Lower Planes, are closed--sealed shut by the power of the True Cross, a holy relic sought by evil thieves who would see the gates to the Lower Planes flung open. Magic exists in this alternate world, but it is less prevalent than in other D&D campaign settings. This paucity of magic serves the core of the adventure's storyline and should be preserved, if possible. This adventure is designed for a party of four 7th-level player characters (PCs). It is recommended that the party include at least one lawful cleric or paladin. Consult the "Adapting the Adventure" sidebar for ways to incorporate the adventure into generic D&D campaigns and modify it for higher or lower levels of play.
