On the bottom-left of the screen you will see the chatbox. In the chatbox you will see four different channels: Whole, Party, Guild and System. Although you can customize each channel the way you want it, by default they’re set to represent their label:
Whole – Displays just about every form of chat, including system and transport messages
Party – Displays party-only chat and whispers
Guild – Displays guild-only chat and whispers
System – Displays system messages and Kartella transport announcements
