200 Million Years AD (New World)

Introduction:

Earth has transformed into an alien world after a gamma-ray burst caused a catastrophic mass extinction, wiping out most dominant lifeforms. Fish and invertebrates were the sole survivors, repopulating the planet and evolving into new, bizarre forms. The continents have merged into a massive supercontinent called Novopangaea (Pangaea II), surrounded by the Global Ocean—the largest body of water in Earth's history. Life now thrives in extreme and isolated ecosystems shaped by aridity, rainfall, and superstorms.

Geographic Features of Novopangaea:

Central Desert – The Arid Heartland:

Located in the continent's center, farthest from the ocean.

Scorching heat, massive sand dunes, and rocky outcrops dominate the landscape.

Life depends on scattered oases and underground reservoirs, remnants of ancient seas.

Inhabitants include Terrabytes, eusocial insect architects, and Garden Worms, photosynthetic burrowers, with Slickribbons hunting in subterranean pools.

Rainshadow Desert – The Flish Graveyard:

South of the Central Desert, cut off from ocean moisture by towering eastern mountains.

Slightly less arid, nourished by occasional superstorms sweeping carcasses of Ocean Flish inland.

Scavenger-based ecosystems revolve around decaying Flish remains, supporting species like Bumblebeetles and burrowing Grimworms.

Northern Forest – The Endless Rainforest:

Located on the northwest coast, drenched by constant rain carried from the Global Ocean.

A lush, temperate rainforest dominated by towering Lichen Trees and teeming with life.

Home to Terasquids like the agile Squibbon and colossal Megasquid, alongside predators like the Stranglesquid and aerial hunters such as the Skyfang Flish.

Eastern Mountains – The Great Divide:

Massive peaks forming a barrier between the coast and arid interior, blocking moisture.

Rugged cliffs and fjords along the ocean provide nesting grounds for Flish colonies and habitats for scavengers like Beachcrawlers.

Global Ocean – The Planet's Dominant Ecosystem:

Spanning nearly three-quarters of the Earth, this vast ocean supports an entirely new marine hierarchy.

Descendants of deep-sea survivors, like Sharkopaths, Rainbow Squids, and Silverswimmers, fill ecological niches once dominated by fish.

Coastal regions are patrolled by Flish, filling the niche of seabirds, and scavengers like Driftclaws and Bonejaw Sharks.

Ecological Highlights:

Deserts of Extremes:

The Central Desert pushes adaptation to its limits, with underground life like Grubroot Worms and Glassfangs thriving in hidden aquifers.

The Rainshadow Desert is shaped by superstorms, sustaining scavenger communities dependent on washed-up carcasses.

Rainforests of Terasquids:

In the Northern Forest, intelligent Terasquids dominate arboreal and terrestrial niches, evolving tool use and social structures.

Oceans of Silverswimmers:

The Global Ocean is ruled by Silverswimmers, crustacean descendants that outcompeted most fish species.

Massive predators like Sharkopaths and Bladewhales enforce new hierarchies, while fish like Spinefins and Bristlejaws occupy smaller niches.

Superstorms as Ecosystem Shapers:

Seasonal superstorms influence migration, food chains, and scavenger surges in the Rainshadow Desert, making weather events critical for survival.

Outro:

Earth, 200 million years in the future, has become an alien landscape shaped by extinction and rebirth. From vast deserts to endless rainforests and oceans teeming with bizarre life, Novopangaea is a testament to evolution's resilience, showcasing how invertebrates and fish-descendants now rule a world once dominated by mammals and reptiles. This is Earth reimagined—wild, strange, and full of life's endless possibilities.
