About the Splash Messages
Splash messages are randomly fetched via API from the Adachi Database, which archives nearly all tweets by @adachirei0.
As of 2026/04/22, the database contains 38786 tweets.
If the client cannot connect to the server, the default Minecraft splash messages will be used instead.
