Once a gifted mortal artisan, Arachne was a weaver whose tapestries were said to rival divine beauty. Her pride, however, grew greater than her talent. She proclaimed her craft superior even to that of the goddess of wisdom and craft.

The gods answered.

Her body twisted but her mind remained. Fingers elongated into needle-like claws, silk began to bleed from her veins, and her lower body split into the abdomen of a monstrous spider. Worst of all — she retained memory of what she once was.

Now she no longer weaves art.

She weaves suffering.

Arachne does not merely kill her victims. She studies them, stalks them, learns their fears… and recreates them in silk. Within her lair hang hundreds of “living statues”: victims preserved in cocooned paralysis, kept alive for weeks while she feeds slowly.

She speaks calmly, intelligently, and politely — like a host welcoming guests.

But she never calls adventurers “heroes”.

She calls them:

“materials.”

Arachne’s Lair

Arachne inhabits ancient, abandoned structures — ruined temples, forgotten underground cities, collapsed castles, or deep cavern systems. Over years, she transforms the environment into a suffocating labyrinth of silk and shadow.

The air is humid and heavy. Every surface — pillars, ceilings, statues, bridges — is covered in thick gray-black webbing. The webs vibrate constantly, allowing Arachne to feel movement anywhere inside her domain.

Dim bioluminescent fungi and cocooned corpses hang from above, gently swaying even without wind.

The lair counts as difficult terrain for all creatures except spiders and Arachne.

Creatures that attempt to sleep inside the lair suffer disturbing dreams and gain no benefit from a long rest unless they succeed on a DC 15 Wisdom saving throw.

Lair Actions

On initiative count 20 (losing initiative ties), Arachne takes one lair action. She cannot use the same effect two rounds in a row.

Living Webs

Webbing erupts from the walls in a 20-foot radius sphere centered on a point Arachne can see within 90 feet.

Creatures in the area must succeed on a DC 16 Dexterity saving throw or become restrained until the end of their next turn.

The area becomes difficult terrain for 1 minute.

Cocoon Drop

Arachne releases suspended cocoons from the ceiling.

Choose up to 3 creatures she can sense through vibrations. Each must make a DC 16 Dexterity saving throw.

On a failure:

• The creature is knocked prone

• Takes 10 (3d6) bludgeoning damage

• And is partially wrapped in silk (speed halved for 1 round)

Shadow Hatchlings

Tiny spiders burst from cracks and corpses.

Swarm of spiders appear in two spaces Arachne can see within 60 feet.
They act immediately after Arachne in the initiative order and obey her telepathic commands.

(The swarms disappear after 1 minute or when reduced to 0 HP.)

Silk Sense

Arachne instantly learns the exact location of every creature touching a surface in the lair until the next initiative 20.

Until then:

• She cannot be surprised

• Invisible creatures gain no benefit against her

Regional Effects

The region within 1 mile of Arachne’s lair is warped by her curse.

1. The Quiet Woods
Natural sounds are muffled. Perception checks relying on hearing are made with disadvantage.

2. Vanishing Travelers
Creatures traveling at night must succeed on a DC 14 Wisdom (Survival) check or unknowingly move toward the lair instead of their destination.

3. The Hanging Dead
Corpses do not decay normally. Within 24 hours, they become dry husks wrapped in faint strands of silk.

4. Arachnid Dominion
Spiders are unnaturally intelligent and will not attack Arachne or her allies.

If Arachne dies, these effects fade over 1d10 days.
