Story Summary: Sophie’s Recording
Sophie’s Identity The NoA terminal in the Tadpole Dock control room reveals a “terrarium” — a virtual personality of Dr. Sophie Boucher, the colony’s surgeon. She left this recording to warn future survivors and guide their actions.
The Situation
- You were meant to go to the desert planet Zezura, but crashed on the ocean planet Proteus
- The colony is destroyed: Chap blew up a bio bed, starting a fire; NoA was forced to open seawater valves, flooding the base. Most colonists died
- Only you and a few survivors remain (Ganzhuo, Liangjingjing, etc.), most missing or driven mad
Macefield Syndrome
- A progressive delusional disorder caused by Proteus’s oceanic environment
- Victims are drawn by the “call of the ocean,” obsess over the distant World Tree, and eventually fall into a trance and drown
- NoA resets severe cases (rolls back to earlier memories), but can’t cure them
- Sophie herself has the syndrome but remains lucid
Nashima
- The colony’s ecologist, also suffering from Macefield but has gone to extremes
- Believes humans don’t belong on Proteus and should be completely eradicated
- Plans to destroy the World Tree (a giant organism supporting a hundreds-of-kilometers ecosystem), causing the food chain to collapse
- Has left the habitat and is heading to the World Tree
The World Tree
- Not a real tree — a giant lifeform, the core energy source of the planet’s ecosystem
- If the World Tree dies, all life dependent on it dies, and humans can’t survive long-term
- It’s also the source of Macefield — its “call” causes the delusions
Your Mission
- Stop Nashima — Sophie believes she’s going to poison or destroy the World Tree
- Head to the eastern Sanctuary, where alien Aksum ruins called “Karakoram” are located
- Install a Depth Module on the Tadpole to reach deep enough areas
- Gain adaptations through Angel Combs and other lifeforms (Digestive, Heat, Pressure)
- Final goal: find Nashima and stop her, while finding a way for humans to survive long-term on Proteus
The Aliens and Sanctuary
- The Sanctuary contains intelligent alien species “Tail Tribe” (Aksum descendants), hostile to humans
- “Sanctuary” is the area around the ruins — humans entering are attacked; Singer was impaled in the chest by a spear
- The World Tree is in the Sanctuary direction
- The ruins may have been left by a civilization older than humanity — possibly also destroyed by Macefield
Farewell
- Sophie admits she may have already died or gone to the World Tree; this recording is just the information she left behind
- She begs you not to give up — the Mingchan still carries 40,000 colonists awaiting a safe home
- “You may be the last human in the entire universe”
Core Mission: Head to the Sanctuary, stop Nashima from destroying the World Tree, while seeking adaptations and the Depth Module to secure humanity’s future on Proteus.
