The Character is the muse that helps you develop personae that:
Will be as real to you as they will be to your readers,
Will be sophisticated and not some simplistic stick figure characters lacking all humanity,
Will not become some overly detailed Freudian masterpiece that only a psychoanalyst could enjoy.
But there is more! The Character:
Will allow you to explore almost without limit any facet of a character's personality that you think is pertinent to your story.
Will even allow you to create a basic sketch for your character's physical appearance!
Permit you to knock out a believable character in a matter of minutes. But if you want, you can spend hours delving into all aspects of appearance, body language, and psychological profile including a built in manual of mental disorders!
Build a database for the characters you create.
Print off a character's biography as a PDF file, an HTML file, or plain text file.
So be it hero, villain, sidekick, mentor, mere passerby, or anything else, The Character allows you to explore to any depth you wish to go.
