The Purson Seal
analyzedThe Purson Seal
A seal on parchment in gold ink, found by Palmer on the wall of Abigail Wright's apartment (Session 4): a complex sigil ringed by letters.

When Palmer lifted it off the wall, a blast of sound came loose with it — a cab honking and someone yelling at the cab. An internet search identified the design as the symbol of a demon of Hell.
Identification
The border letters read P · V · R · S · O · N → PURSON. Purson is a Great King of Hell in the Ars Goetia (the Lesser Key of Solomon): said to know hidden things, find what is concealed, and reveal past, present, and future. Gold-ink Goetic seals are drawn exactly this way — the spirit's name set in letters around the sigil.
Analysis
It Was Holding a Piece of the Street
The seal had a **fragment of New York** sealed under it; unsticking it released the captured sound. This is the same containment behavior as the impossible rooms in Session 3 — places and moments held inside objects.
- Gold ink again — the medium of the Rooftop Symbol, the gold-ink symbol in the case file, and the The Carcosa Song.
- A named Goetic demon is now on the board. Abigail had its seal on her wall.
The Gold Seal Reappears (Session 7)
A **gold Goetic seal in the same style** — a sigil ringed by its spirit's name — rides the **coded letter hidden inside The Zielony Invitation** (Box 13 HQ, on-screen). The exact spirit isn't yet identified, but the medium and form match this one. The Goetic apparatus (Purson, Seere, the Hygromanteia) now travels **on invitations**, not just apartment walls.
