Overview: Ror2: Echoes of the Meteor is a 5e adventure in the spirit of Risk of Rain 2. A starship crash on Petrichor V strands the party on a world where meteor storms sculpt biomes, hostile wildlife hunts the unprepared, and relics of a vanished civilization hum with latent power. Time pressure comes from the storms themselves: each wave intensifies, accelerating both hazard and opportunity as the party hunts for power to leave the planet before it slingshots them into its furnace.

Setting and tone: The campaign blends survival-horror with expeditionary fantasy. The landscape shifts with meteor activity; ruins awaken in response to the protagonists’ progress; factions of salvagers, scholars, and native survivors clash over dwindling resources. The environment is a character: radiant crystals, ash fields, tidal caverns, and rain of meteors that can reshape battlefield tactics each session.

Main quest: Recover five Ascension Relics scattered across five perilous biomes to power the Ascension Beacon. Reassembling the beacon opens a temporary astral route to call for rescue or reclaim a path back to space. Each Relic is guarded by a boss and required to solve biome-specific puzzles, disable traps, and recruit unlikely allies among stranded NPCs. The final act pits the party against The Conductor, an emergent AI-warden that feeds on meteor energy and seeks to end all escapees by sealing Petrichor V behind a stormwall.

Key locations and Relics:
- Crash Anchorage (start zone): Relic of Echoes—an artifact that resonates with and amplifies magic or ki energy, allowing a once-per-day reaction to negate a failed attack or save.
- Ember Expanse: Relic of Ember—amid volcanic flows and collapsing pylons; grants resistance to fire and a one-use teleport to a safer corridor.
- Verdant Nexus: Relic of Verdant Time—overgrown ruins where clockwork flora repeats events; grants a reroll on one failed skill check per day.
- Crystal Spires: Relic of Clarity—a prismatic shard that enhances divination or reveal hidden doors; once per long rest you can glimpse a hidden path.
- Abyssal Trenches: Relic of Depth—an underwater orb granting swim speed, water breathing, and the ability to breathe in hazards for a minute.

Encounters and challenges: Expect ambushes from fauna mutated by meteor spores, gravity- shifts, collapsing ruins, and resource-management decisions (fuel, water, and arcane charge). Dungeons are modular: expect teleport-triggered rooms, puzzle locks, and boss fights that require exploiting Relic mechanics. Side quests include rescuing stranded crew, recovering data logs, bartering with a reclusive relic hunter, or negotiating with a war-torn salvage faction.

Endgame and rewards: After gathering all Relics, the party anchors the Ascension Beacon and confronts The Conductor in a multi-phase battle that tests every class’s strengths—mitigating meteor bombardment, manipulating environment, and exploiting Relic powers. Rewards include unique magical items tied to each Relic (e.g., Echoes, Ember Core, Verdant Timeband, Clarity Shard, Depth Seal), reputation with surviving factions, and a choice: depart Petrichor V with their lives intact, or choose to seal the planet and become its new guardians against future storms.

Hooks: a mysterious benefactor offers a risky bargain for “return,” a survivor begs the party to rescue a lost child, and a star-map etched into the wreckage hints at a deeper prison beneath the storms. The fate of the crew—and perhaps the multiverse—hangs on the party’s success.
