Huanca

## Paradise Habitability

## About

**Huanca** (also known as **TRAPPIST-1d**) is the third planet from TRAPPIST-1 and the first planet you need to complete before playing the rest of the TRAPPIST-1 story campaign. This planet is an "eyeball" planet, as one side has land and the other side has liquid water. Completing Huanca will unlock the rest of the TRAPPIST-1 planets, except for Ostara, which will be unlocked after the entire TRAPPIST-1 system is finished.

Huanca does not have natural satellites.

> We hope to eventually settle all worlds in this system, but first we need to establish a solid foothold.

> Our generation ship contains supplies for hominizing Huanca, and only after we have successfully that world can we attempt to tame the more hostile planets near it.

## Strategy

You need to spend 20 culture points to win on a TRAPPIST-1 world, so put down a city, put down an extra habitation, and wait in the game for 20 culture points from random events, or use the strategy below.

When the pressure levels increase, the sea levels will also increase, so we need to research geocisterns and/or ice launchers, as well as building spaceport facilities in the cities to increase population and money.

You can also build cities on the dark side (and also the watery) part of Huanca because there are some islands there. For best results, build cities near or at the twilight zone, where water meets with land, because this is the most habitable zone of this planet.

## Trivia

* Huanca (TRAPPIST-1d) is in the conservative habitable zone of its star. It is the closest to the host star out of all the habitable planets with an equilibrium temperature just a bit colder than Earth’s, at around 282.1 K (9 °C).
* This planet is an **eyeball planet**, because one side too hot, and the other full of ice since it's tidally locked to TRAPPIST-1. And in the twilight zone, there may be some liquid water on the surface. If it had an ocean and thick enough atmosphere, heat would be distributed more evenly.
* A 2018 Study led by the University of Washington suggests that TRAPPIST-1d could be a Venus-like world with an uninhabitable atmosphere. Suggesting that it may not be a habitable world.
	+ Although, considering that the two inner planets of TRAPPIST-1 were discovered to not be Venus-like worlds, its possible that the same might apply to TRAPPIST-1d if the 2018 study is correct.
* The dark side might harbor liquid water instead of ices.
* TRAPPIST-1d is the least massive planet in the TRAPPIST-1 system, with its mass just shy of 30% of Earth. It is also almost as dense as the moon, making it radius 78.4% as big as Earth and gravity around half of that on Earth. That means you would jump twice as high on TRAPPIST-1d than on Earth.
* The description of this world says that they reached TRAPPIST-1 in eight generations. Assuming that a generation is 30 years and the distance between TRAPPIST-1 and Earth is 39.46 light-years, the speed they traveled would be around 16.5% the speed of light.
* Huanca, or Huaca, are Inca gods of rocks and nature.

## Victory — Spoiler Alert

Instead of spending culture points on independence, on this world and other TRAPPIST-1 worlds, culture points are spent on investigation and decryption. Victory is achieved when you spend 20 culture points on this, regardless of whether you have achieved the faction's secondary goals.

*"Upon landing on Huanca, our scientists began picking up strange signals coming from beneath the surface. The signals are weak and intermittent, but each time they cycle we become more convinced of the impossible: that we are detecting an ancient alien device, long left abandoned by its creators. If we can find this device, who knows what we could learn from it?"*

*- investigation: Each step brings you closer to the device.*

"*Your scientists have found the device, but cannot understand it. It seems willing to interface with our systems, but it is simply too alien to be intelligible. Our best linguists are working on it, though, and we hope to have an answer soon."*

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

After completing Huanca, you will be allowed to use the Tresuunak on subsequent TRAPPIST-1 worlds, allowing you to access the Satellites tab early.

### Victory Text

*Aliens.*

*For centuries we have wondered if we were alone in the universe, the only species capable of exploring the stars. Well, now we have our answer. After generations of work in the most momentous hominization effort in the history of humanity, Huanca is now home to [number] people. It is a hub of culture, learning, and innovation, a shining jewel in humanity's burgeoning interstellar community.*

*And most breathtaking of all: the ship. After centuries of study, our scientists have finally learned enough about the alien structure to deduce its true purpose. It is a ship, massive in scale, designed for interplanetary and interstellar transport. Preliminary translations seem to refer to it as the Tresuunak, a name derived from the mythology of the long-forgotten alien race. The tale speaks of a great adventurer who built a ship to explore the heavens, but before she could conquer them she would need to recruit help from 'the sea, the sky, the past, and the future.' Our scientists don't know what this refers to, if anything, but studies are ongoing.*

*In the meantime, the Tresuunak is ready for launch. It could prove to be a huge help in our continuing exploration of the TRAPPIST-1 system, for not only will we be facing the usual dangers of hominization and terraforming, but there will no doubt be other alien devices on these worlds as well. Even more intriguing, the Tresuunak seems to have several empty slots where other components could be installed. Who knows what the ship will be capable of, when fully upgraded?*
