The Cognomina Underground Grotto is both a hidden meeting place and the ceremonial center of the Cognomina. Reached by a long staircase beneath a modern city, it gives the society’s history a physical form: a cavern shaped by successive religious and civic uses, now arranged for judgment and initiation. Evan Michaels first enters it as a candidate awaiting the Ascension; after the judges accept him, the grotto becomes the setting of his welcome into the group.

Location and history

The grotto was once part of an old church. For hundreds of years, the Cognomina paid tribute to the church in exchange for access. After the church was destroyed by fire in 1743, the society bought the ruin and built an edifice over its foundation and the grotto. The chamber therefore predates the building above it, while its continued use reflects the Cognomina’s long-standing presence there.

Its deeper origin is uncertain. Poppy tells Evan that no one knows exactly how old the grotto is, but she guesses that Romans excavated it as part of a temple, possibly a Mithraic one. That suggestion remains a conjecture rather than a confirmed history. The space is old enough to invite competing layers of explanation, but its documented connection to the Cognomina is the society’s centuries-long access and its later acquisition of the ruined church site.

Descent and interior

Evan reaches the chamber by descending between seventy-five and one hundred stone steps. Torches fixed to the walls provide the faint light, while the old masonry offers fissures and ledges along the way. The brass tip of his cane clicks against the steps and sends echoes down the stairwell. The descent is not simply a change of level: it carries him from the familiar modern world into an enclosed space whose darkness and scale delay his full understanding of where he has arrived.

At the bottom, the stairwell opens into a large cavern. A dozen thick stone columns support its high ceiling; intricate scrollwork decorates the tops and bottoms of the columns. Rough-faced stone forms the walls, and dark, polished granite in the floor creates a subtle mosaic that catches the torchlight. Silver-footed stands hold large torches around the room. The chamber’s considerable size is made palpable through sound as well as sight: footsteps, clothing, and the cane’s taps reverberate around the stone interior.

The room is furnished for formal proceedings. A simple wooden table and two chairs stand near the center, facing a long wooden console like a judge’s bench against the back wall. To one side, two rows of tiered seats form a gallery in front of a heavy black curtain that reaches from floor to ceiling and spans the room’s width. The curtain conceals more of the grotto, making the visible hearing room only part of a larger complex. Poppy says the festival will be held in that larger section, which Evan has not yet seen.

The grotto as a place of judgment

The room’s layout makes the Ascension hearing a public test rather than a private exchange. When the curtain moves aside, the judges enter first, wearing white robes with black trim, and take their places on the bench. Other members follow in ordinary clothes with narrow black-and-red silk stoles, then fill the gallery. They proceed in silence and at measured intervals; their accumulated footsteps make the assembly’s presence unmistakable to Evan.

Behind the judges hangs a spear about the length of a man, with a black spearhead and a red-dyed horsehair skirt. Its white wooden shaft and tip bear crusted brown blood. The weapon recalls the Cognomina’s former method of testing a candidate: members would run the person through with a spear, and acceptance followed only if the candidate returned in a later life and identified the person who had killed them. In the present-day procedure, a panel instead weighs verifiable evidence—names, dates, places, and other details from a previous life. The spear thus remains in the chamber as a reminder of an older ordeal, even though the hearing Evan faces depends on testimony and judgment.

Ceremony and significance

At Evan’s hearing, the judges determine by a vote of four to one that he is who he claims to be and will be welcomed into the Cognomina as a brother. The decision transforms the same chamber that had made him feel like an uncertain outsider into the setting of his acceptance. Samas embraces him; relief and celebration spread through the gallery, where cheers and groans also accompany the settling of wagers.

The welcome continues beyond the verdict. Evan addresses the gathered members and calls the community home. The musicians stop while he speaks, leaving the breathing in the room and the crackle of the torches to carry through the columns; when he jokes that the society has spared his life, the gathering answers with hoots and howls, and the music resumes. Poppy then presents a fingerless leather gauntlet fitted with an Embe-shaped template, through which Evan is to receive the tattoo worn by members after Ascension. The grotto therefore joins several stages of admission in one setting: the candidate descends into the hidden society, faces its judges beneath the relic of its harsher past, receives recognition, and proceeds toward a bodily mark of membership. Its concealed architecture makes that change visible as a passage from the world above into the Cognomina’s shared history.
