Geography & Surface Features:

• Continents / Oceans: No continents — 98% covered in deep ocean with scattered archipelagos of floating biotic landmasses

• Terrain Highlights:

  • ☑ Deep trenches (up to 30 km)

  • ☑ Hydrothermal vents

  • ☑ Floating kelp forests

  • ☑ Coral-like megastructures

  • Other: Submerged cave networks

Lifeforms:

• ☑ Microbial

• ☑ Plant-like (photosynthetic algae)

• ☑ Animal

• ☑ Intelligent

• Notes: Bioluminescent fauna dominate, most life adapted to high pressure and low light. Apex predators include 50m-long leviathans.

Civilizations (if any):

• Species Name(s): Pelari

• Technology Level: Mid-tech aquatic civilization — uses bioengineering and sonar-based architecture

• Culture / Society Notes: Nomadic ocean dwellers organized into pod-tribes. Rituals center on celestial tides and symbiosis with native fauna.

Additional Notes:

• Floating city-colonies tethered to nutrient-rich thermal plumes

• No metallurgy; all tools crafted from coral, chitin, and crystal

• Unique language based on clicks, flashes, and pressure pulses
