The Player Character is the main protagonist of Star Stable and serves as the players avatar in-game. The character never speaks and it's with almost no exception always the player that has to imagine how the character is feeling, is thinking or is saying. It's only possible to play as a girl. The player character is described by the characters in the game as helpful and friendly, but again,there is no evidence about how the character acts or feels.
In some quests, the player has to choose between a few answers to move the dialog and complete the quest, and that is the only time the player character clearly shows what she is saying.
