Lyra and her brother, Eldarion, were patrolling the lines between Minas Tirith and Osgiliath, they never expected anything to come try to fight them but they had to be prepared. Eldarion looked at her, "Lyra, father has something he needs to tell you when you return. I don't know what it is but he wants you back before dark so he gets the chance."
Lyra blinked at him, for this had come out of nowhere. She pulled the reins back on her horse, Kuran, to stop him as she looked after her brother. They then turned and rode back towards the White City, all the while Lyra was thinking about what her father wanted to tell her.
