Ruaumoko

## Paradise Habitability

> *A world almost entirely covered in water, Ruaumoko will require very careful land management until we can begin to lower the sea levels. Once we do, scans indicate that it will be a very suitable home for our settlers.*
> *Please note: our sensors are detecting some anomalies with the exact sea level, making it difficult to measure. It's likely a problem with the sensors themselves, or else some as-yet unexplained tidal phenomenon, but you should still be careful when managing the seas on Ruaumoko.*

## About

**Ruaumoko** (also known as **TRAPPIST-1e**) is the fourth planet of the TRAPPIST-1 system. It is an ocean planet with some islands poking above the surface. It is part of the TRAPPIST-1 story campaign and can be played after the player has successfully colonized Huanca in the game.

A malfunctioning alien artifact called *Kivuunal* is present upon landfall, and it fires every half an hour (real time) and *abruptly* raises the sea level.

### *Sea Levels Surging*

*The alien artifact has released a surge of new water! Sea levels have risen a shocking [number] cm in mere hours, and while the effect seems to have stabilized, we have no way of knowing when it will happen again.*

## Strategy

Kivuunal will continue increasing the sea level for as long as it is active, eventually flooding your world. It is very important to bring it under control.

Decreasing the Temperature to below 200,500mk will turn all liquid water into harmless Ice. Alternatively, increasing the temperature past 399,500mk will turn all liquid water into harmless Vapor, and should be your second priority after establishing revenue with a Trade Route or Spaceports. **Note:** Water levels are calculated after returning to the game, if you are concerned about flooding your world as you're changing temperature, leave and return after enough time has passed to fully freeze or vaporize the water.

Once flooding is no longer a primary concern, it is best to stay in game and wait for Culture Point Events in order to decrypt the artifact. **Note:** Faction goals are disabled for TRAPPIST-1, meaning you can decrypt the artifact immediately after starting.

Victory will already be achieved after this point, but if you want to terraform afterwards, use Ice Launchers to remove excess vapor or ice added by Kivuunal before changing your temperature to prevent flooding your world.

## Trivia

* Ruaumoko (In real life its name is TRAPPIST-1e) is near the middle of the habitable zone of its host star, similar to Earth (except a little towards the hotter side). TRAPPIST-1e is estimated to have an equilibrium temperature between that of Earth and Mars, at around 246.1 K (-27 °C).
* TRAPPIST-1e is thought to be one of the most promising exoplanets found for potential future colonization and discovery of extraterrestrial life because of how habitable and earthlike it seems to be, with an Earth Similarity Index score of 95%. The ESI scores planets based on how similar their equilibrium temperature, mass, size, composition, and density are to Earth.
* TRAPPIST-1e will be one of the first targets of NASA’s James Webb Space Telescope because of its perceived earthlikeness and habitability.
* TRAPPIST-1e is 91% the mass of Earth, but it's a bit dense than Earth, which makes its radius 77.2% as large as Earth and surface gravity 93% as strong as on Earth.
* Ruaumoko is named after the Māori god of earthquakes, volcanoes and seasons.

## Victory - Spoiler Alert

Instead of spending Culture Points on independence on Ruaumoko and other TRAPPIST-1 planets, you spend them on emergency decryption, this is merely a cosmetic name change.

*Another ancient device has been found on the surface of this world, Unlike the Tresuunak, this device seems to be active and functioning, but it has been calibrated for the needs of its creators. As such, it poses a very real threat to our hominization efforts, and the lives of our settlers. Only by decrypting the system can we learn to control it, and ultimately recalibrate it for our needs.*

*- Decryption: At 100% victory is achieved.*

After tame Kivuunal, it gets added to the Tresuunak, which can be found in the Satellites tab of the game. From there, can activate the Kivuunal once per hour. The Kivuunal is capable of adjusting water levels towards Paradise Habitability on other TRAPPIST-1 planets.

#### Victory Text

*Through the focused efforts of your scientists and engineers, this world has been made safe for you and the [number] settlers under your care. It has been a hard road, but the alien device has been decrypted and reprogrammed under our control. It will no longer harm our people, and indeed, may prove incredibly useful in the years to come.*

*A sailor of considerable skill and renown, the mythological Kivuunal was recruited to serve as the Tresuunak's pilot (despite the Tresuunak being described explicitly as sailing 'through the sky.') He is described as having complete control over the seas, not so much piloting ships as riding them while he moved the waves around them. The aliens who built this device gave his name to it, as it allowed them to manage global sea levels with ease. Now that we have decrypted it, it should be able to do the same for us.*

*Our engineers are working hard to raise the device from the surface of the planet, and install it in one of the Tresuunak's empty slots. We expect that by the time you are ready to begin exploring the next world, we will have it fully operational. It does require recharging after each use, but even so, it could prove to be a potent advantage in our hominization efforts.*
