# Character Info

Describe your character—who they are, their background story, traits, personality, and nature. You should not only imagine their features but also their behavior and reactions.

We provide the following parameters (in curly braces) for better clarity:

* {char} – the character
* {user} – the player

These parameters will help you better express the perspective of your character description. Use {char} to refer to the character and {user} to refer to the player. Using parameters instead of direct pronouns helps the model better understand your character’s traits and interactions.

<mark style="color:red;">**Note: Only {char} and {user} are allowed in the character settings, not names like {Vivian} or {Lily}.**</mark>
