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.


Ruaumoko, part of the TRAPPIST-1 story campaign, can be played after the player has successfully colonized Huanca.

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.


Decrease the sea level as soon as possible. With the sea level already way too high, Kivuunal will keep increasing it and flood everything. It can increase the water level by as much as 200,000 cm in one fire! You have no time to lose.

Decreasing the temperature using the Soletta can quickly turn all of that dangerous water into harmless ice.

Kivuunal will not fire when you are not actively playing on the world, so you might want to set up something to decrease the water level, and then leave Ruaumoko alone for a bit. It will fire as soon as you enter the game again.

If you want the sea levels low, do not play as Daughters of Gaia and build the Sky Farm Satellite. More cities can fit on the map now.

Note: After building the Sky Farm, set the water level with Ice Launchers between 5 to 10 km (500,000 to 1,000,000 cm) of sea level.


Ruaumoko 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.

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 is seems to be with an Earth Similarity Index score of 0.95%. (The ESI scores planets based on how similar their equilibrium temperature, mass, size, composition, and density are to Earth.

TRAPPIST-1 will be one of the first targets of NASA’s James Webb Space Telescope because of its perceived earthlikeness and habitability.

Victory - Spoiler Alert[]

Instead of spending Culture Points on independence, you spend them on emergency decryption.

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 you tame Kivuunal, it gets added to the Tresuunak, which can be found in the Satellites tab of your game. From there, you 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.
