The Shifting Wane
Domain of Chaos Beyond the Outer Planes

The Shifting Wane is not a true world, but a churning storm of unstable reality. Beyond the reach of the Outer Planes, it pulses with arcane entropy. Terrain flickers in and out like smoke, barely stable enough to support life. Obsidian-eyed flora shimmer silently, and whispering woods murmur forgotten names. The bruised violet sky crackles with filaments of living magic, flickering like silent lightning. Distance bends and loops—one step forward may send you back, altered or doubled.

Rivers of silver liquid spiral up cliffs and into the air, humming strange tunes that hint at prophecy or erase memory. Islands of stability drift through the chaos, bound to the whims of sleeping god-minds. Wildlife here is a blur of echo, plant, and beast—ever-shifting forms shaped by chaotic arcana.

Geographic consistency is fiction. Biomes vanish and reappear like a dreaming god’s afterthought. Glass-bone trees emit mood-altering spores. Floating continents drift in nonsense orbits, lined with levitating moss and sentient coral. Chasms radiate light. Lakes reflect speculative futures. Maps are useless—today’s glade might be tomorrow’s crystal inferno.

Creatures survive by adapting to the Wane’s chaos. Evolution bends to magic. Predators phase through planes; prey split into mirror selves. Magic saturates biology—grazers grow anti-scrying crystal skin, and fungal bugs share psychic minds. Even mundane animals can trigger spell effects: fear spawns darkness, birdsong reverses gravity. In the Wane, magic isn’t a tool—it’s the apex predator.

Rules of the Wane: Arcane Distortion
Magic here is volatile, semi-sentient, and dangerous.

• Unstable Casting. When casting a 1st-level or higher spell, roll a d20. On a 1–3, the spell misfires—its effect or target is altered.

• Arcane Feedback. On a spell attack roll of 1, or if a creature saves against your spell by 10+, take force damage equal to twice the spell’s level.

• Spell Echo. On a natural 20 when casting, roll a d6. On a 6, the spell duplicates instantly.

• Wild Arcana Surge. The first spell cast each day triggers a roll on the Wane Surge Table.

• Magical Terrain Reaction. Spells cast within 30 ft. of arcane terrain may trigger a magical event (e.g., time loops, gravity shift).

Rules of the Wane: Reality is a Fluid Concept
The world denies stability—adapt or unravel.

• Gravity Flux. Once per long rest, the DM may declare a gravity shift for 1 hour (e.g., sideways or upward).

• Rotating Safe Zones. At dawn, roll a d6. On a 1, rest offers no relief. DC 15 Con save or gain a level of exhaustion.

• Time Fracture. Upon entering a new area, roll a d10. On a 1–2, 1 hour for you equals 8 outside—or vice versa.

• Memory Tangle. After long rest, DC 14 Wis save or forget a key detail from the prior day.

• Wane Affliction. After 7 days in the Wane, DC 15 Cha save or gain Echo Taint (visions, magical bleed, side effects).
