Some words deserve their moment.

Entrust them to Sylorkey. They will open only at the moment you have chosen.

Enter

Sylorkey opens the door
to a new world.

A galaxy of countless worlds, each inhabited, each unlike anything we know. Your messages cross time there: write, record or film, choose the exact date of the revealing, and entrust it to a Sylor Guardian. It will open only at the chosen moment.

Countless worlds
Each one holds life
A single key to open them

Moments that wait

For whom, for when?

A Guardian keeps a message until the day you choose. Here is a moment that could be sealed today.

The guardians

The Sylors

The Sylors are the mystical guardians of Sylorkey. These creatures watch over the relics and stay with every sealed message until the moment it is to be revealed.

Astria is the first of them: the Guardian of Novure, world of eternal ice, its unique code hidden beneath the cloak. Entrust it with a message: it will open only on the date you have chosen — a birthday, a coming of age, a homecoming.

  • Every Sylor carries a unique code
  • One message per Guardian, sealed once
  • Opening protected by a password

World of eternal ice

The Sylorkey shop is not a catalogue: it is a galaxy. Every world shelters its Guardians, and every Guardian keeps a message for time to come. Novure is the first world to open, and Astria its first Guardian, now on pre-order.

The concept

Understanding the Sylor concept

Send a message into the future that will reveal itself at exactly the moment you choose. A Guardian, a message, a moment: that is all it takes to seal an emotion.

01

A Guardian

Every Sylor is a Guardian: a unique relic, born of a world in the Sylorkey galaxy. Astria, Guardian of Novure, carries a unique code hidden beneath its cloak. It alone can open the emotion it keeps.

02

A message

Text, audio or video: you create your message in the app, then seal it with a password that only you know.

03

A moment

You set the exact date and time of the opening, from a few hours to several years away. Until then the message stays sealed, invisible to everyone.

“Some messages are not made for today… but for the exact moment when the future reveals them.”

How it works

Everything happens in the Sylorkey app, free on iOS and Android. The Guardian is the key; the app is the lock.

  4. 4Set a date and time for the opening
  5. 5Create a password to open the message
  6. 6Choose the recipient (optional)
  7. 7Seal your message

The message will be accessible only at the moment you have chosen.
A message sent into the future, protected until its moment.

Receive

Receive a message

  1. 1Type the 8-character code engraved beneath the Guardian's cloak (not the “N° SK-…” number just below it)
  2. 2Enter the password set at sealing
  3. 3The message is revealed at exactly the chosen moment

Your message is biding its time, protected, invisible to everyone…
Be patient — the revealing will come at the chosen moment.

The Guardian

Astria physically keeps your message until the opening date you have chosen.

In the app

Without a Guardian, a message can also be sealed in the app, with an opening up to 5 years ahead.

A gift

Give the Guardian to whomever you choose: they receive a companion to keep close, then, at the chosen moment, your message.

Questions

Frequently asked questions

What is a Sylor?

A Sylor is a Guardian: a unique relic, born of a world in the Sylorkey galaxy, which keeps a message sealed in time. At launch one world is open, Novure, and one Guardian is on pre-order, Astria. Every Guardian carries a unique code; that code, together with the Sylorkey app, is the only way to open the message.

Is it a time capsule?

In a way, yes. You seal a text, audio or video message with a password, and it opens only on the date and at the time you have chosen, not before. Except that this capsule has a Guardian: Astria, which you keep close from the day it arrives, while the message waits for its moment. A double gift, then: one right away, the other at the chosen moment.

Where is Astria's code hidden?

At the back, beneath its cloak. It exists only once and binds your Guardian to the message you entrust to it, and to no one else.

How does the pre-order work?

You order and pay for Astria now, by card. Your Guardian belongs to the first edition and ships in December 2026 and is delivered by 31 January 2027 at the latest. You receive a confirmation email straight away with your order reference. As with any distance purchase, you have fourteen days after delivery to change your mind and be refunded in full.

Does the recipient need the app?

Yes. The Sylorkey app, free on iOS and Android, is where the Guardian's code and the password chosen at sealing are entered. The message is revealed only at the date and time that were set, not before.

Can I give Astria as a gift?

That is exactly what it is for, and it makes a double gift. You seal a message, then give the Guardian: it stays with the recipient from that day on, while the message itself opens only at the moment you have chosen.

Can a message be sealed without a Guardian?

Yes. In the app, digital Sylors are bought in packs, with an opening up to 5 years ahead. You can also give one to someone who has the app. Only a Guardian physically keeps the message.

What happens if I lose my Guardian?

The message stays sealed, and nothing is erased. The Guardian's owner declares it lost in the app: the message is then blocked. If the Guardian turns up, the owner unblocks it. Otherwise, the owner transfers the message to a new Guardian, never sealed before, with the password chosen at sealing.

And the Fragments?

Other relics will appear before long in the Sylorkey universe. They are not included in the Astria box and are not yet on sale.
