Because there was so much to test out, and Nial was in need of a mountain of resources, he spent more than a day conquering dungeons. He experimented a lot as well, but he couldn't quite get a hang of the Vengeance of Chaos ability even after he sorted his thoughts.
Nial now knew that the Orin family was not related to him by blood at all. That didn't mean his love and care for them would suddenly disappear, but it made him wonder who he was and where his biological parents were.
If they were dead, did he have some other relatives he didn't know about?
Why did the Oracle ask if he was human?
Was he really born in Jundra, or did he emerge from the other side of the irregular dungeon portal 22 years ago?
There were dozens of similar questions tormenting his mind, and they didn't disappear even after he told himself that everything was fine.
