        The mint unicorn, he decided, was behaving much like a well-trained guard dog.  After he had approached no closer, she had returned to scanning the area around her, but every time she turned in his direction, she fixed him with a steady gaze, reminding him that she was keeping track of his presence, and while she would tolerate him as long as he stayed out of her territory, she would not let him approach without facing consequences.  Closer observation showed that she always kept one ear cocked in his direction, even when she looked away, and he noticed that the other creatures were often keeping their ears pointed at her.  He idly wondered what they would do if he moved closer, but reminded himself that the soldiers were wearing armor and carrying weapons, so he supposed that they were probably capable of dealing with him.
