What is a Talk Profile?: A zeta Talk Profile is a feature that allows users to register or change their own fixed settings and avatar information for each individual talk room (chat). Key Features: Deepening the world-building and relationships. You can individually specify the relationship with the character and the user's settings (name, appearance, position, etc.) within that specific talk room.
Actions in zeta: When a character in zeta performs an action, the words are enclosed in "*" to indicate the behavior.
