The Shattered Sanctuary of Dhaerax

Deep in the forgotten reaches of the ruined city of Dhaerax lies a sanctuary once revered for its ancient divination techniques. Created by the enigmatic Omerth, a prophet who dared to commune with the stars, this temple has been sullied by greed and despair. Its halls, hidden within a decaying ziggurat, now echo with the whispers of lost knowledge and fragmented souls, creating a treacherous labyrinth for those bold enough to seek out the sanctuary's legendary power—the Starshard Compass, said to guide the user towards their deepest desire.

As the adventurers stand at the threshold of this crumbling edifice, they can feel the pulse of its ancient magic radiating from the stone walls, bated in an atmosphere thick with foreboding. It is here that they will face forgotten guardians, eccentric denizens, and strange phenomena, each challenging their intellect and resolve.
