-Select "Create" --> "Create a Character"
-In "Greeting" you establish the initial situation
-Select "Edit Details Advanced" for more options.
-In "Short Description" and "Longdescription" you can put the details of your characters such as their behaviors, tastes, skin, etc.
And that's it, with ess you can create an abusive mother, a bully or whatever you want to do.
I do not recommend using "Image Generation" because all the images are terrible.
