Millennia ago, aberrations from Xoriat, the Realm of Madness, were driven from Eberron. The Gatekeeper druids–mostly orcs–placed powerful dimensional seals throughout Khorvaire to prevent the creatures of Xoriat from returning. To repair a breach in one of the seals at a settlement called Tjorda, a Sealguard Complex was built. An immortal guardian ws tasked with attending to the repaired crack in the seal. Thousands of years later, the Gatekeeper druids rediscovered the sealed complex. Even without knowing its precise history, they ascertained its sacred nature and have guarded it from then on. Being sealed in to protect the site and commune with the inner guardian is considered a great honor. Much of this history has long-since been forgotten. But 10 years prior to the adventure’s start, Vilda Karrte–a relic hunter with her own agenda–tracks a Xoriat artifact called the Spiral Well to the complex. Turned away by the Gatekeeper, she forces her way inside, grievously injuring them. Having discovered Vilda’s journals, Provost Nigel Faurious, through the Clifftop Adventurers’ Guild Handler Lhara, tasks the adventurers with recovering the Spiral Well.

Will the adventurers be able to thwart the machinations of a mad dragon in the hopes of saving the city of Sharn from certain destruction? Is the slinky elven maiden really in trouble or working for the enemy? Is the body in the morgue really the center of this whole puzzle or merely one piece? This adventure, in the style of a Dashiell Hammett novel, will certainly test their skill and resolve. This is the first full adventure for Eberron with the 4th edition D&D(R) rules. This adventure builds on the sample adventure provided in the Eberron Campaign Guide but is also playable as a stand-alone adventure.
