Because he had the Seed of Sunlight, Eliard was much stronger than before. His five senses were much more sensitive too.
For example, he heard some abnormal noises now. In reality, the High Elves should be more than 3000 feet away and hadn't discovered them yet.
Eliard had many choices now. The safest one was to abandon the woman who'd kidnapped him and escape alone. The High Elves would leave after finding this woman. But after thinking, he didn't choose that.
She was only working with Morpheus. If I find the right method, I can make her turn around and join Ferde. At that time, we'll become even stronger.
Eliard found a high and mighty excuse for himself. Now that he had a goal, he had to think about what to do next.
All his power was sealed; he couldn't use anything. The only thing he had was a body stronger than the average man. With the Sunlight Power, his body was like a Level-6 Warrior.
