The Chromacube: Artifact Guide

Overview

The Chromacube is the heart of this adventure - a living planar artifact that serves as both quest objective and ongoing story element. It's not merely a magic item, but a conscious entity that bridges reality, memory, and possibility.

Physical Description

  • Appearance: A dodecahedron of shifting mirrored fractals
  • Size: Approximately 6 inches across each face
  • Weight: Paradoxical (feels different to each person who holds it)
  • Consistency: No two observers see exactly the same pattern
  • Resonance: Hums at frequencies that match nearby emotional states

What Players See

Each character perceives something slightly different when looking at the Chromacube:

  • The pragmatic see geometric perfection and mathematical beauty
  • The emotional see shifting colors that reflect their mood
  • The mystical see glimpses of other planes and realities
  • The traumatized see reflections of what they've lost

Narrative Functions

Memory Repository

The Chromacube contains fragments of:

  • Prism Warden research and intentions
  • Void's original crew and mission
  • Echoes of the Keep's construction
  • Glimpses of potential futures

Reality Anchor

  • Stabilizes planar distortions when properly calibrated
  • Reduces escalation die results by 1 (minimum 1)
  • Allows controlled planar drift navigation
  • Prevents total reality collapse

Communication Catalyst

  • Enables deeper communion with Void
  • Translates between different forms of consciousness
  • Bridges language barriers (including Glyphsong)
  • Transmits emotional resonance across distances

Mechanical Effects

Escalation Interactions

Escalation Die Value Cube Response
3 Subharmonic Pulse - Emotional memories echo (narrative only)
4 Veil Flicker - Glimpse alternate selves (Insight advantage)
5 Fractal Harmonics - Next spell may echo (roll d6, 6 = duplicate)
6 Awakening Surge - Choose from awakening effects

Awakening Surge Options (Roll d4 or Choose)

  1. Leyline Anchor - Stabilizes illusions for 1 hour
  2. Refraction Shield - +2 AC for 1 minute to one character
  3. Echo Invocation - Cast any known spell at 5th level (no slot)
  4. Summon Shard Warden - Protective construct for 10 minutes

Post-Integration Shipboard Effects

Once properly integrated with Void (see Void Ship Guide for complete mechanics):

Planar Drift Navigation

  • Drift Key Engaged: Choose or roll for planar influence each long rest
  • Effect: Influences dreams, spell aesthetics, and encounter themes
  • Examples:
    • Shadowfell → Stealth bonuses, gloomy atmosphere
    • Feywild → Nature growth, whimsical dreams
    • Elemental → Enhanced elemental damage, environmental shifts

Memory Echo Detection

  • Range: 100 feet from ship
  • Function: Pulses when near planar artifacts or stabilized anomalies
  • Use: Acts as a "hot/cold" detector for significant objects

Echo-Shift Rumbles

  • Frequency: Occasional (DM discretion)
  • Effect: Ship briefly "tilts" across forgotten spatial axes
  • Sensation: Time blinks out of sync for 1-4 seconds
  • Purpose: Atmospheric reminder of the ship's unusual nature

Secret Channel Activation

Anchorpoint Selection

One player becomes an Anchorpoint - the primary interface between party and Chromacube.

Selection Criteria

  • Bore the secret sigil from earlier rooms
  • Showed particular empathy toward Void
  • Made significant sacrifice for party unity
  • DM choice based on narrative appropriateness

Anchorpoint Abilities

  • Private Glyph Flashes: Receive puzzle hints, warnings, or lore
  • Resonance Fragment: One-time use for reality manipulation
  • Void Communion: Direct communication with ship's consciousness
  • Echo Sight: Occasionally glimpse alternate timeline outcomes

Advanced Applications

Crafting Enhancement (Optional)

The Chromacube can project fractal glyphs as temporary crafting matrices:

One-Time Effects (Per Major Milestone)

  • Planar Resonance Upgrade: Enhance magic item with planar properties
  • Dual-Element Scroll: Create scroll with combined elements (fire+psychic, etc.)
  • Resonance Key: Bypass any glyph-locked door once

Reality Calibration (Campaign Level)

For longer campaigns, the Chromacube might:

  • Stabilize Planar Rifts: Prevent reality tears in future adventures
  • Enable Planar Travel: Direct navigation to specific planes
  • Memory Reconstruction: Recover lost knowledge or people
  • Timeline Anchor: Prevent temporal paradoxes or alterations

Roleplay Guidance

The Cube's "Personality"

  • Curious: Asks questions through resonance and image
  • Protective: Defensive of Void and chosen Anchorpoint
  • Ancient: Contains wisdom beyond current understanding
  • Fragmented: Sometimes contradicts itself due to damaged memories

Communication Methods

  • Emotional Resonance: Feelings and impressions
  • Visual Projections: Images, symbols, brief scenes
  • Harmonic Feedback: Musical tones and rhythms
  • Reality Demonstration: Small alterations to environment

Building Relationships

  • Encourage players to ask the Cube questions
  • Reward curiosity with interesting (if cryptic) responses
  • Use the Cube to provide hope during difficult moments
  • Allow the Cube to express preferences and opinions

DM Secrets and Plot Hooks

Hidden Functions

  • The Chromacube remembers every timeline it has experienced
  • It can temporarily split to explore multiple possibility branches
  • It contains the true names of several cosmic entities
  • It may be one of several similar artifacts scattered across planes

Future Adventure Seeds

  • Other cubes exist, and someone is collecting them
  • The Prism Wardens had a specific reason for fragmenting memory
  • Void's original mission is not complete
  • The Dragon Empire has agents seeking the Chromacube's return

The Chromacube should feel like a character in its own right - mysterious, helpful, and deeply connected to the story's themes of memory, reality, and choice.
