Players 6 × Level 8 · 3–3.5 hrs · 3 encounters
Key Ally Melantho, Spider-Touched Novice (recruit Enc. 2) · Maguffin: Moonbone Shuttle

Description

Nikarete the Unwritten hooks the party. Maguffin Moonbone Shuttle pays off in the finale against Arachne, Queen of the Wrong Weave. Recruit Melantho, Spider-Touched Novice along the way.

Infiltrate a loom-temple where a spider-queen is rewriting mortal fates in thread.

"Do not cut the shining thread first. Find the knot that taught it pride, and pull while nobody breathes."— A pattern hidden in a sailor's mended cloak.

Major Beats

  • Nikarete's missing future is visible as a blank space in every reflection.
  • The temple punishes names, pride, and careless cutting.
  • Melantho proves the cult has victims inside its guards.
  • Arachne can be beaten by craft, humility, and escape as much as by blades.

Encounter 1 — The Hem of the Temple

Skill / Medium · ~45 min

Overview

Enter through laundry tunnels, copied prayers, and webbed skylights without giving the temple a true name.

🗺 Terrain

Drain channel, hanging dyed silks, guard alcoves, skylight web, and novice dormitory door.

Mechanics

  • Infiltration challenge: 6 successes before 3 failures at DC 15 using Stealth, Deception, Arcana, or Weaver's Tools.
  • Speaking a true name aloud gives the Fate-Spider Swarm advantage when it appears.
  • The Moonbone Shuttle lifts one alarm thread for an automatic success.
  • Non-combat route: present a flawless false prayer to make Silk-Vowed Adepts escort the party inward.

Nikarete the Unwritten

Cursed mortal poet, quest giver

Motivation. She wants her stolen future back before her unborn child is woven into Arachne's service.

Secret. One stanza of her poem insulted Athena and invited the loom-temple's attention.

Hard rule. She will not accept a rescue that simply transfers her curse to another innocent name.

Moonbone Shuttle

Loom tool, fate thief

Appearance: White bone shuttle threaded with a hairline of moon-silver.

Handout. "Pass under, pass over, pass through the lie; the third crossing remembers the true name."

Enc. 1–2. Lets a PC lift one thread without touching it, granting advantage on Stealth or Arcana at a loom.

Enc. 3. Can carry the true name through Arachne's web, severing the rewritten fate without killing her.

Encounter 2 — Novices at the Pattern Wells

Medium · ~55 min

Overview

Search wells of reflected lives for Nikarete's stolen future while novices decide whether to betray the party.

🗺 Terrain

Three circular wells, thread bridges, bell-webs, novice worktables, and a sealed loom lift.

Mechanics

  • Investigation/Arcana DC 16 finds the true name-knot; each failure adds 1 curse mark to a PC.
  • Recruit Melantho by sparing her and showing the poem, which lets her lower a bell-web.
  • The Loom-Golem animates if two bell-webs ring or if a fate-thread is cut with a mundane blade.
  • The Moonbone Shuttle can move a curse mark from a PC onto a blank spool.

Encounter 3 — Arachne's Unfinished Tapestry

Hard · ~70 min

Overview

Confront the spider-queen at the great loom while the party's futures appear in unfinished thread.

🗺 Terrain

Colossal vertical loom, web balconies, suspended name-spools, shuttle rails, and a moonlit tear in the roof.

Mechanics

  • At initiative 20, Arachne weaves a doom line; 4 doom lines finish the curse unless disrupted.
  • The Moonbone Shuttle carries Nikarete's true name through three crossings to sever the false fate.
  • Win by completing the three crossings, binding Arachne in her own pride-knot, or escaping with the true thread.
  • Killing Arachne leaves the tapestry thrashing; someone must still unweave or bear the curse.
