By using the application form you can set a custom title. This title can be activated in the title interface afterwards. (Each character can only have one custom title. By using another application form you can change the custom title.) Note: no spaces are allowed in the title.
The custom title appears above your character's name. This title appears ONLY on the character it is applied to, it does not apply to all characters on an account. Each character can have one and only one "Custom Title". Using another of this item replaces the first title with a new one.
