Lytalia

Lytalia was a female Phiadoran who was saved by Turlough from a terrible fall. He became attracted to her, because of their slender bodies. Using a touch of his forehead, she could speak English.

Upon arriving on her species' camp, she introduced them to the princess Nareena. She gave the rest of her race the power to speak the language.

When heading for the citadel, Turlough was disappointed to note that she was forced to go in a group in front that would scout for any dangers. She realised his disappointment and promised that she would return when her job was over and join him. (PDA:  Imperial Moon)
