Formless Spawn

Description

A black, oozing protoplasmic mass that shifts and writhes, forming and reabsorbing limbs, mouths, and eyes in a constant state of flux. It fills whatever space it occupies like a living liquid, squeezing through gaps and reshaping itself to grasp or strike. An amorphous, protoplasmic Mythos entity summoned during the secret ritual at the Goupil Masquerade in Lyon, rising through an aperture in the floor of a hidden chamber beneath Maison du Corbeau.

Encounters

Chapter 2 — Goupil Masquerade

The investigators attended a masquerade soirée at Maison du Corbeau, hosted by Lucien Goupil but orchestrated by Mathilde Savarin. Behind the social facade, a secret ritual took place in a hidden chamber. The Formless Spawn rose through an aperture in the floor. A child was sacrificed with a tuning-fork blade in the same ritual. The investigators witnessed everything and did not intervene.

This was the party’s first direct encounter with the Choir’s supernatural horror — the moment the campaign’s threat became viscerally real.
