Talk to others using a language you can speak and it scrambles text you can't understand into several fantasy scripts.
Features
Chat
A language selection dropbox is available above the chat text box so you can select which language you want your character to speak in.
When loading a world, only the last 100 messages are scrambled to avoid making load times insane on a big chat log.
Journal
You can write text in a specific script and only players who speak that language will understand it. If they understand the language, hovering over the text will show the language's name.
Custom Languages
You can add your own languages to Polyglot by inputting them into a module setting.
Supported Systems
Aria, D&D 3.5e, D&D 5e, Dark Heresy 2e, The Dark Eye 5e, Dungeon Crawl Classics, GURPS, Old-School Essentials, Pathfinder, Pathfinder 2e, Savage Worlds, Shadow of the Demon Lord, Starfinder, Shadowrun 5e, WFRP4e
Other Systems
Other systems can still use Polyglot as long as there's items on the actor's sheets. You must add create items under the Language (Foo) pattern, which will make the character be able to speak the Foo language.
Remember to add the languages to the Custom Languages setting to be able to change its alphabet (you'll notice it isn't there because the name on the selector will be lowercased).
