The Dome

The Dome & The Lost City of Zindariel

Location: Deep in the coastal highlands of the gnomish nation, now quarantined and declared forbidden by the Arcane Council.

Overview: Once a shining marvel of arcane innovation, the city of Zindariel is now entombed within a mysterious, 50 mile radius sphere of churning green mist known only as The Dome. No wind can disperse the fog, and no conventional magic can pierce it. Within, reality itself fractures.

Origin of the Disaster

Zindariel's greatest minds constructed the Arcanum Engine, a revolutionary device intended to unify and regulate magical frequencies across the city. It worked—until it didn't. When the Engine failed, it tore open a permanent rift between life and death, twisting the city and its surrounding landscape into an arcane wasteland.

Current Conditions Inside the Dome

The Fog: Dense, luminous green mist that churns like a living entity. No wind affects it. Visibility drops to a few dozen feet.

Magical Warping:

Necromancy:

Conjuration & Healing:

Illusion & Enchantment:

Wild Magic Surges:

Necrotic Pull: Life ebbs unnaturally. Death saving throws are difficult . Long rests may fail to restore.

Reanimation Effect: Corpses reanimate within hours unless burned or beheaded.

Construct Ban: Constructs (warforged, golems, summoned objects) shut down upon entry.

Mutation Exposure:

Minor Mutations (hours):

Major Mutations (days/permanent):

Key Landmarks

The Verdant Gate: A half-collapsed portal covered in vines and ancient glyphs. It occasionally pulses, and strange mutated creatures sometimes emerge from it.

The Silent Spires: Towering ruins of Zindariel's arcane academies, visible through the mist like broken fingers. Some glow faintly. All are haunted.

The Breach: The cratered heart of the city, where the Arcanum Engine once stood. Constantly emits blue-green lightning. Said to be the eye of the storm.

The Cradle Gardens: Once a botanical paradise, now a grotesque jungle of sentient, mutated flora. Every plant is hostile, and none survive transplant beyond the Dome.

Villages Trapped Within

Cricklehaven

Thallid's Verge

Tinker’s End

Duskgrove

These villages are now warped reflections of themselves, isolated and strange. Some remain partially inhabited—others are overrun with mutation and madness.

Rumors from the Dome

1. The Heart Moves: The Breach slowly shifts its location every decade. The center of the Dome is never where it used to be.

2. Whispering Mist: At night, the fog whispers names—sometimes the names of the dead, the lost, or those yet to enter.

3. Reality Tears: Stepping in the wrong place might send you to another plane (usually the Shadowfell... but not always).

4. Ghost Keys: Floating spectral keys occasionally bond to explorers. They unlock any lock—once. Then they vanish... and something about you might disappear too.

5. The Undead Court: An ancient council of Zindariel's nobility still meets in their ruined palace, plotting their resurrection.

6. The Clean Zone: A 500-foot bubble near the old university where magic functions normally. No one stays there long—everyone feels watched.

7. Living Tattoos: Magical tattoos that slither off the dead and seek new hosts. Some grant power, others drain the soul.

8. The Bell Tower Still Rings: Randomly, a ruined tower tolls. Those who hear it either vanish, go mad, or kill indiscriminately.

9. Child's Laughter: Heard deep in the mist. No child is ever found. Those who chase it never return.

10. The Arcanum Engine Lives: Some theorists believe the Engine didn't break. It evolved. It is cocooning the city, waiting to hatch.
