Ostara

## About

**Ostara** (**TRAPPIST-1g**) is the ending part of the TRAPPIST-1 storyline. It has a thick green atmosphere with a yellow-brown surface. To unlock this, we need to colonize all the other planets in the TRAPPIST-1 system.

Ostara, like any other TRAPPIST-1 world, does not have natural satellites.

All artifact events that have been dealt with on previous TRAPPIST-1 planets randomly occur here, though it's still only one event per half an hour. These can be viewed here.

## Unlocking

Ostara is rather difficult to unlock. After buying the TRAPPIST-1 campaign, you will need to colonize Huanca (TRAPPIST-1d), after which you can colonize five other worlds (except for this one). Only after you've done all that is Ostara finally unlocked.

Text after colonizing Huanca, but before completing the rest of TRAPPIST-1:

*Even after all we've learned of this system, none of our ships or scans has penetrated the atmosphere of Ostara. Perhaps the Tresuunak will be able to do so, but we dare not make the attempt until it is fully upgraded. Continue exploring the system, and return when only this world is left.*

## Strategy

   Ostara is like Venus with extra challenges. Its atmosphere crushes the buildings, but it also has all of the artifact events of the other TRAPPIST-1 worlds.

Just like on Venus, first set up something that can earn money by building two or more cities with a trade route. Research the hydrogen processor, build some of those, and then leave Ostara alone until its atmosphere has paradise conditions and you have money to spend. Don't use mines, as they are useless and will deplete after just a short time. If you stick to mines, wait for the paydirt event to pop up. This will be easy, and the mines will last longer.

Remember that as long as you don't log in and view Ostara, none of the facility-crushing events will happen, so whatever you've built is completely safe. The best way to play Ostara is to leave it alone for as long as possible (which means you can leave it alone for as long as you're sure the cities won't flood), amassing tons of resources, which you spend on increasing the economy and population, and by that point you've probably got the 20 culture points you need to decrypt the artifact and render it harmless.

Also remember to use the artifacts on the Tresuunak that you've collected on other TRAPPIST-1 worlds. You can access these right from the start. There is no need to build a spaceport first.

## Trivia

* + Ostara (TRAPPIST-1g) is in the optimistic outer-edge habitable zone, where water is less likely to pool on the surface but still could if the atmospheric pressure and composition are right.
	+ TRAPPIST-1g is thought to have a thick atmosphere that has hundreds of bars of abiotic oxygen and water vapor pressure. Its surface might be a global ocean of water.
	+ If it has no atmosphere, it might have a thick ice shell with a subsurface ocean beneath its surface.
	+ The blue-green objects on the ground in Ostara are two Tresuunak launch pads. in the middle and on the edge
	+ TRAPPIST-1g has roughly 115% the mass and radius of Earth, though its density is only 4.186 g/cm3, about 76% of Earth's.
* Ostara is the Old High German name of the goddess Ēostre, the west germanic spring goddess.

## Victory — Spoiler Alert!

Instead of spending culture points on independence, on this world and other TRAPPIST-1 worlds, people devote culture points to 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.

*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.*

#### Victory Text

*Home.*

*[Number] people now call this world home. It was hard-fought, the culmination of everything we've learned from the alien artifacts and from TRAPPIST-1 itself, but we've done it. The final piece of an alien technology has been decrypted and tamed, and a second, fully operational Tresuunak-class ship has been launched, complete with all the upgrades we worked so hard to gain for the original.*

*To the disappointment of our scholars, the final piece of the myth of the Tresuunak seems to have been lost. Several databanks were destroyed by either time or the struggle during our hominization, and could not be recovered. We will never know how these beings thought the tale of Dvintek, Qelsetk, Kivuunal, Metuurein, and Vuuresal ended. But in our own way, we have repeated the process, defeating a great monster to forge our own home among the stars. Perhaps that is as good an end to the story as any.*

*But of course, the story never really ends. Humanity has built a new home here, on seven thriving new worlds. And with the aid of our two Tresuunak ships, some people are already discussing moving beyond TRAPPIST-1, further out into the galaxy in pursuit of other adventures and the fate of those who built these miraculous machines.*
