Stonehenge Ritual

Overview

On the night of the New Moon, June 12, 1814, the London cell of the Aeternum Choir — operating under the cover of the Orphean Society — attempted Segment I of the Grand Canticle at Stonehenge on Salisbury Plain. Dr. Erasmus Hume, the cell’s High Conductor, led the ritual with Lady Octavia Danforth as his deputy. The ceremony called for blood sacrifice and harmonic invocation to open a dimensional seam and invite the attention of Yog-Sothoth.

The ritual achieved a partial manifestation — luminous orbs of immense size pressed through the fabric of reality, and the stones themselves began to resonate — before the investigators disrupted the harmonic sequence. The investigators had ridden ahead of the cult’s procession to Salisbury, where they recruited local farmers from a pub and planned a two-pronged assault: farmers attacking from one end of the stone circle as a distraction while the PCs assaulted from the other. The farmers went in first. Both Hume and Danforth were killed during the disruption. All five members of the original party survived: Marina Garrick, Emma Wentworth, Georgiana Wentworth, Charlotte Thorne, and Augustus Bolt.

The failure of Segment I marked the first confirmed disruption of the Aeternum Choir’s global ritual programme. Intelligence recovered from the cult’s paraphernalia pointed the Order of St Aelfric toward Lyon, where a second cell — the Société Harmonique de l Aube — was preparing its own Canticle segment.

Sequence of Events

• ~22:00 — A procession of carriages arrives at Stonehenge. The convoy carries Hume, Danforth, six core cultists in black robes with silken vocal masks, the bound Order captive Nathaniel Rooke, three “failed” students marked for sacrifice, and a wagon of ritual paraphernalia including brass tuning forks, engraved resonance bowls, a portable harmonium, and the Canticle fragment on vellum.
• 22:30–23:45 — Pre-ritual preparations. Candles and pitch bowls erected at the compass points of the stone circle. A circle of salt and silver dust laid across the central altar. Tuning crucifixes — large X-shaped frames carved with sigils — erected along the solstice axis. Hume tunes harmonic forks to the lunar rise. The stone circle begins to pulse with a sub-audible bass note that causes nausea and nosebleeds in the uninitiated.
• 00:00 (June 13) — The Canticle begins. Hume sings the opening verses. Danforth conducts the cultists in a five-part harmonic chant. The sacrificial victims are bled; their dying sounds are captured in resonance bowls. The bound Order captive’s vocal cords are stimulated with tuning forks, producing inhuman sounds against their will.
• Shortly after midnight — A dimensional seam tears open in the centre of the stone ring. A partial manifestation of Yog-Sothoth occurs: luminous orbs of vast size press through the air, a roiling mass of translucent light threaded with mathematical glyphs appears, and the blood of the sacrifices is drawn upward into geometric shapes rotating in pentagonal formations.
• Disruption — The investigators intervene. The harmonic sequence is broken. The manifestation collapses. The cult is thrown into chaos.
• The farmers attacked from one side of the stone circle as a distraction. All seven volunteers reached the circle. Several were killed, including Alfred, who had joined with six farmers.
• The investigators assaulted from the opposite side. The investigators took gunfire. Hume struck Charlotte with Spectral Razor, cutting her diagonally from shoulder to hip and leaving a lasting scar.
• Marina Garrick ended up directly beneath the forming summoning creature.
• As the assault cut off the ritualists one by one — then Hume, then Danforth — the summoning lost coherence and collapsed, dripping acid onto Marina.
• Hume and Danforth were both killed. Nathaniel Rooke was rescued from the tuning crucifix before Danforth could reach him.

Aftermath

Imogen Bellamy had already been rescued from the Orphean Society sub-basement before the Stonehenge assault. Nathaniel Rooke was freed from the tuning crucifix during the battle itself.

In the days following the Stonehenge disruption, the party was formally inducted into the Order of St Aelfric under Lord Harcourt’s authority. The ritual’s failure confirmed that the Aeternum Choir’s Grand Canticle could be stopped — that human action at the point of invocation was sufficient to break the harmonic chain.

Intelligence recovered from the cult’s ritual site and surviving materials pointed to Lyon as the location of the next active cell. Harcourt dispatched the party to France, beginning the journey that would lead to Chapter 2 and the confrontation with Mathilde Savarin and the Société Harmonique de l Aube.

Unresolved Questions

Campaign Significance

The Stonehenge Ritual was the campaign’s first full-scale ritual confrontation. Everything before it — the investigations through London’s musical salons, the mapping of the Orphean Society’s hierarchy, the tracking of Hume and Danforth — had been preparation. At Stonehenge, the investigators witnessed the Aeternum Choir’s true ambition made manifest: a globe-spanning cult capable of tearing open reality through coordinated musical invocation.

Three truths were established that night. First, the Grand Canticle is real — the cult possesses the knowledge and the will to invoke Yog-Sothoth through harmonic ritual. Second, individual segments of the Canticle can be disrupted by direct intervention at the ritual site. Third, the Choir operates across multiple cities and nations, meaning the threat cannot be ended by destroying a single cell. The intelligence trail leading to Lyon confirmed a network of at least eight ritual sites worldwide, and the campaign’s central question took shape: can the investigators disrupt enough cells to prevent the Grand Canticle from reaching its threshold?
