It's not like this is the first time [2]

It was getting dark, thus making it harder to walk, to deal with this I used my elemental magic and created a fireball to illuminate the surroundings. 

The area came to light. Surprisingly, this wasn't as big of a tunnel as I was expecting it to be. The width was around 7 to 8 meters and the overall passageway was shaped in an oval design.

There wasn't much to say, as nothing major happened during this time. Challes was angry because I'd left the adventurers to die, but not that it mattered to me, but due to that, he was behaving rather not normally. 

It was his body language that told me, instead of his usual walking style, he was taking short, reserved steps. His hands hanging down in ease and his head tilted, eyes staring at the ground. It was as if he was angry but didn't want to show it since there was nothing he could do about it.
