Asterism Open the sky
Open to everyone

Collect the night sky.

Real stars. Numbered cards. One shared sky.

The stars are real. Your cards and Astra are kept on your Sigil account.

How it works

Four things to do

Explore

Drag to look around a real night sky and zoom in on any star.

Inspect

Fly in to a star, calibrate the telescope and scan every world around it, one at a time. Finishing an inspection teaches you about the star and earns Astra.

Collect

Spend Astra on packs of numbered cards: stars, planets and more. Collect the key stars of a constellation to finish its set.

Contracts

Short jobs in the real sky: find a star from a few clues, spot the one that moves, or work out what is strange about one. They pay Astra.

Real events appear on the map in the week they happened. A supernova, a gamma-ray burst or the first picture of a black hole can be watched for Astra, once a year.

The cards

Every card is its own

A card is one numbered copy of a star. Two copies of Rigel look the same except for their number and their brilliance: a rating from 0 to 5, rolled at random once when the card is made and never changed. The brightest copy of a star in a server makes its holder that star’s Keeper.

  • Real stars, with their real colours and designations.
  • Famous stars have no price anywhere. They only turn up, very rarely, in the Featured pack, which arrives in a later update.
  • Collect a constellation’s key stars to finish its set.

Astra and Dark Matter

Two currencies, both earned or given, never sold

Astra

The everyday currency. You earn it by inspecting stars and spend it on packs. You cannot buy it, and you cannot send it to another player.

Dark Matter

A rarer currency for one special pack, the Dark Matter Cache: black holes, neutron stars and other exotic objects. Sigil Ember members receive a fixed amount every week. It cannot be topped up with money.

Neither currency turns into the other.

In Discord

The sky is on the website. Your cards come to Discord.

Open packs and show your cards in any channel with the /sky command.

Questions

Good to know

Is it free?

Yes. Exploring, inspecting stars, contracts and opening packs with Astra are all free. Sigil Ember members get a fixed weekly amount of Dark Matter on top.

Is it gambling?

Packs are random, like packs of trading cards. But you cannot buy Astra, packs or cards with money, and nothing in the game can be cashed out. The only paid part is the weekly Dark Matter that comes with an Ember plan.

Are the worlds around each star real?

No. The stars are real, but the worlds around them are simulated, and labelled that way.

What does it need in my server?

The /sky command needs the same basic permissions as the rest of Sigil (send messages, embeds and attach files) and never needs Administrator.

Who is it for?

Anyone who likes stars or collecting cards. A few minutes at a time is enough, there is no fighting, and everything in it is about space. Discord’s age rules apply.
