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.
