Planescape: Harbinger House (Thursday Evening)

Planescape: Harbinger House

Originally published for Advanced Dungeons & Dragons. Adapted for D&D 5.5E (2024).

Welcome to Sigil: the City of Doors, the Cage, the crossroads of the multiverse. A place where every faction has an angle, every alley hides a portal and the Lady of Pain enforces a silence that the city's residents have learned to respect.

A murder has drawn you in. It should be straightforward. It is not.

The deeper the investigation goes, the stranger the connections become, between madness and prophecy, between divine power and mortal minds, between what people believe and what they are capable of becoming. In Sigil, these threads are never as separate as they seem.

Harbinger House is a classic mystery-driven adventure originally written for Advanced D&D and brought forward into 5e, one of the most beloved and distinctive adventures from the original Planescape line. It rewards curiosity, careful attention, and the willingness to follow a thread even when it leads somewhere deeply uncomfortable.

The setting is unlike anything else in D&D. Beginner friendly, the story pulls you in before the lore does.
