Campaign: The World is Stopping

Location: The Dal-Dur Mountains, The Clockwork Heart, Dal Dur Deep Core Level Range: 12-17

Campaign Overview & Themes

• The Core Conflict: The flow of Aethervale's ambient magic, time, and the synchronization of its core temperature are regulated by an ancient, planet-sized mechanism known as the "Chronos-Clock," located deep within the Dal-Dur mountains. The Clock is seizing up. The grease of time is drying out, caused by a temporal anomaly known as the "Stillness." Spells are hanging in the air, days are getting unnaturally long, and entire villages are becoming frozen in localized time-bubbles. The players are contacted by "Tick-Tock," a maddened, ancient dwarven mechanic of the Gear-Bound, to find a way to lubricate the gears and defeat the entities of the Stillness before the world freezes forever.
• Tone & Tropes: High-concept cosmic fantasy and bizarre temporal mechanics. Themes include the inevitability of decay, fighting against the fundamental laws of physics, and surreal, mind-bending environments where time is broken.

The Sandbox / Regional Guide

• Base of Operations: The Pendulum Station. A massive, swinging platform located in the upper shafts of the Chronos-Clock. It exists in a pocket of stable time. The players can rest here, trade with eccentric extra-dimensional merchants who have gotten stuck, and research temporal magic.
• Key Locations:
  • The Stilled Wastes: Areas of the Dal-Dur mountains where time has completely stopped. Entering requires special temporal tethers; otherwise, players risk becoming frozen like statues forever.
  • The Gear-Plains: A massive subterranean landscape made entirely of interlocking gears the size of cities. Navigating it requires anticipating the massive, grinding movements of the terrain.
  • The Anomaly Epicenter: A localized black hole where time is running backwards. Exploring this area causes characters to "un-learn" skills or physically regress in age if they stay too long.
  • The Temporal Vaults: Ancient libraries where refined aetheric oils and reserves of liquid mana meant to replenish the Aether-Spills (the shimmering curtains of liquid mana already actively lubricating the gears in the Clockwork Heart) are rumored to be stored, guarded by paradox-creatures.

Factions & Reputations

• The Gear-Bound (Tick-Tock's Faction): A tiny group of immortal, clockwork-augmented dwarven mechanics trying to maintain the machine. They are logical to a fault and lack empathy, viewing the players purely as tools to fix the machine.
• The Void Gazers: A cult that worships the freezing of time as the ultimate peace and salvation from suffering. They actively sabotage the players' efforts to restart the clock.
• The Paradox Echoes: Violent manifestations of alternate timelines that were "pruned" by the Chronos-Clock in the past. They hate the current timeline and want to ensure it ends.
• The Chrono-Dragons: Metallic, time-traveling dragons that police the timestream. They are neutral but will attack the players if they believe their actions will cause a worse temporal paradox.

The Villains & Lieutenants

• The Big Bad: The Null-Entity. A systemic glitch of pure anti-time originating within the fabric of the multiverse. It feeds on kinetic and temporal energy. It is not malicious; it is a fundamental force of entropy that has latched onto the Chronos-Clock like a parasite.
• The Timeline of Doom:
  • Month 3: Localized "time-freezes" become common. Major cities experience "stuttering," where people lose hours of memory or repeat the same day.
  • Month 6: The planet suffers extreme core temperature drops, initiating the "Arcane Frost." Magical fracturing spreads across the globe, making magic highly unstable, with spells casting hours after they are triggered.
  • Month 12: The Chronos-Clock stops completely. The Null-Entity consumes the remaining energy, plunging Aethervale into the Arcane Freeze, locking the world in absolute stillness and killing all magic-born creatures.
• Lieutenants:
  • High-Priestess Aethel: The leader of the Void Gazers, who wields powerful localized time-stop magic.
  • The Grand Paradox: An amalgamation of three different failed timelines, functioning as a chaotic, unpredictable assassin.
  • The Rust-Behemoth: A manifestation of the Clock's decay, a massive elemental that consumes metal and time.

The 5-Act Structure

• Act I: The Inciting Incident (Levels 12-13): The players experience a "time-skip" during a battle in the Dal-Dur mountains, suddenly finding themselves miles away, hours later. They discover a frozen village and are pulled into the earth by a mechanical tendril deployed by Tick-Tock, who frantically explains the situation.
• Act II: The Sandbox (Levels 13-14): The players must explore the Gear-Plains and the Stilled Wastes to gather the components for the "Temporal Tethers" needed to survive deep within the Clock. They must deal with the Void Gazers sabotaging the upper gears.
• Act III: The Turning Point (Levels 14-15): The players delve into the Temporal Vaults to retrieve the refined aetheric oils. During the heist, they are ambushed by the Grand Paradox. Defeating it causes a temporal feedback loop that permanently alters a major historical event in the world above (DM's discretion on how this changes the campaign map).
• Act IV: The Escalation & Assault (Levels 15-16): The descent into the Clockwork Heart. The players must navigate the incredibly dangerous, seizing machinery. They must fight off Chrono-Dragons who view their intervention as a paradox. They confront and defeat High-Priestess Aethel, who is attempting to perform the ritual to merge her soul with the central spindle.
• Act V: The Climax (Levels 16-17): The final confrontation with the Null-Entity at the absolute center of the world. The battle takes place in a void where the laws of time are breaking down. The players must fight the entity while simultaneously applying the refined aetheric oils to lubricate the massive, seizing central spindle, allowing the Pendulum of Ages to swing freely and pass through the Ignition Spark, which inherently restarts the Aether currents.

Dungeons & Set Pieces

• The Anomaly Epicenter: A reverse-dungeon. Gimmick: Players start at the "boss room" and must fight their way out to the entrance. Any damage taken is "healed" over time, but spells cast return to their slots after a delay, creating a confusing resource-management puzzle where players must spend resources to progress backwards.
• The Seizing Gear-Plains: A moving puzzle dungeon. Gimmick: The map consists of multiple massive rotating gears. Every round, the gears rotate 90 degrees. Players must position themselves correctly to avoid being crushed between the teeth of the gears, while fighting enemies that can freely teleport between the cogs.
• The Core Spindle (Final Dungeon): The battle against the Null-Entity. Gimmick: At the start of every round, the DM rolls on the established d20 Temporal Glitches table to determine the flow of time in the chamber, as the core spindle introduces a unique, localized extreme version of the anomaly.

Evolving Loot & Vestiges

• The Chronos-Key: A complex, glowing pocket watch.
  • Dormant (Level 12): The user can cast Misty Step and Blur. They have advantage on initiative rolls.
  • Awakened (Level 14): Once per day, the user can cast Haste on themselves without requiring concentration. When an enemy misses them with a melee attack, the user can use a reaction to age the enemy's armor or weapon, giving a -1 penalty to AC or attack rolls (stacks up to -3).
  • Exalted (Level 16): Once per week, the user can take an additional turn immediately after their current turn ends. They can touch a willing creature and completely reset their status (HP, spell slots, conditions) to exactly what it was 24 hours ago.
• Aegis of the Immutable: A breastplate made from the polished casing of a Chrono-Dragon.
  • Dormant (Level 12): Grants advantage on saving throws against being stunned or paralyzed, and the wearer's movement cannot be hindered by difficult terrain.
  • Awakened (Level 14): As a reaction to failing a saving throw, the wearer can choose to succeed instead by "stepping slightly out of time," but they cannot move on their next turn (once per long rest).
  • Exalted (Level 16): The wearer gains a constant aura (10 feet). Enemies within the aura cannot take reactions, and their movement speed is halved as time thickens around them.
• The Shard of Absolute Time: A jagged fragment of crystallized entropy awarded upon the defeat of the Null-Entity. It grants the wielder immunity to the Slow spell and any effect that would artificially age them, and allows the casting of Time Stop once per week.
