But from another perspective, Orgar didn't die, so he couldn't be revived… Ryan couldn't help but wonder if Alissa had those questions in her mind. She probably thought of that, and that was why she was looking for the knowledge of dragons. The older they are, the more knowledge they have, after all.
Nakine said that the trio would last for six hours, but since Ryan was using Soul Eater, it only took them one hour to reach the region where the battle had taken place. There were some mountains here and there, but overall, the place was basically a massive grassland… a massive grassland that was trembling in hundreds of kilometers in all directions because some crazy individuals were fighting.
