The Cathedral Slug

What it looks like, and what it does

A vast pale body, grey-lilac and glistening, crossing a field. On its back a slate-roofed stone chapel, grown into the mantle like a shell. A trail of slime a hundred metres wide that holds a faint reflection of the sky. Tiny lit windows.

Circles the same river valley. Rests in winter. Grazes grass and the lichen on gravestones, and leaves the churchyards it passes cleaner than it found them.

What is known

First recorded in a parish register of 1740 as “the Slow Parish”: a village that moves four metres a day. The maps of the district have been redrawn six times.

The congregation, about eighty, holds services daily. They say they have never travelled. Visitors who step off at the edge describe the land sliding past like a river.

What it can do

• Carries a stone chapel and its congregation across open country at four metres a day
• Heals the surfaces it crosses: cracks close, moss and lichen clear from stone

Where it stops

• Cannot climb; it goes around every hill, however long that takes
• Stops at dusk for the vigil and will not move until the last hymn is finished

An encounter

Achterberg preached in the chapel and found the congregation warm, curious and entirely certain. They asked how the weather was in “the moving country.” Her sermon had been about distance. She recorded that she had never felt so far from anyone.

What is established, and what is only said

• established: Surveys over 280 years show a closed circuit of about 91 kilometres, completed roughly once a decade.
• rumor: That the congregation can hear the bells of the villages it has left.
• interpretation: It may not be carrying the chapel. The chapel may be what it is making, one slow step at a time.

Still unresolved

It has never been seen to turn back. Everyone inside was born inside. What is the destination, and do they want it?

Where it has been recorded

• The Vale of Aldermere (confirmed) — Recorded by Revd. Josephine Achterberg, visiting priest.

Stories about it

• The Parish That Moves Four Metres (Entity story, 3 min) — A parish priest on St Brannoc's Hill discovers that his church is slowly sliding down the slope on the back of a slug the size of a village, and the congregation has never once noticed the ground under the nave is moving.
• Notes from a Moving Parish (Diary fragment, 1 min) — A week in the diary of someone who has begun to doubt that the chapel is standing still.

Connected entities

• Gravel Lamb — Both change the distance between places: the lamb shortens a road, the slug lengthens a valley.
• The Ship That Grows — Both are communities carried by a larger body on a circuit. Both are looked after by the people they pass.
• The White Procession — Both are processions that other people have organised their lives around. Neither has been seen to arrive.
