Hello, Rokisha. Please enter your character's name for this task.
Wait unil you launch the game the first time. It will ask you for a "character name" input what you want, and after you do the first tutorial task press the `P` button to bring up your character sheet. Make sure you are viewing the Attributes tab. Your character name will be in the top left.
