As many people quickly realized, the initial image was written in
Aurebesh, the fictional script of the Star Wars universe. It reads, in Spanish, "Vaya a nuestra Discord y reaccione," which translates to "Go to our Discord and react."
Of course, this was not merely a plug for our Discord. Quite a few people showed up on our Discord server, trying to find the next step. Many of them attempted to trigger the bots, such as our custom-written Zaphyr, to respond with something. However, the solution lay elsewhere.
Discord has reactions, in the form of emojis. Servers can
add custom emojis, which is what we did. I made
this 32x32 image to fit within the Discord emoji constraints, handwriting the letters in a small pixel-based font of my own design. As far as I am aware, The Peninsular#7987 is the only person to have found this emoji as the solution, and they have my congratulations.
Looking at the contents of the emoji (which can be downloaded and zoomed-into through various ways), the letters themselves are text encoded in MIME base64. Decoded, we get this URL:
wintreath.com/index.php?part=2048
Which leads us to a game of 2048!
But the tiles look rather odd...
