Connect your Minecraft account to your Discord account with the server's linking bot.
Join the Age of Elysian Discord, then run /discord link in Minecraft. Click the six-digit code in chat to copy it, then send it to the server's bot in a private Discord message. Don't post the code in a public channel; it expires after 24 hours.
The bot confirms when the accounts are linked. To check your link later, run /discord linked in Minecraft.
