Unlike the Kobolds, who were used to living underground, Lux was having trouble adapting to the environment.
Everywhere he looked, there was just dirt. The smell of soil also permeated the surroundings. Eiko, on the other hand, seemed at ease, and just stayed on top of Lux's head for the duration of the expedition.

"Let's camp here for now," Cadmus said after they arrived in a small enclosed cavern. "Did you bring food with you, Half-Elf?"
"The name is Lux, and yes, I brought food with me," Lux replied as he summoned a basket of sandwiches that he had asked the Tavern Cook to make on short notice.
Eiko happily took a bite of the sandwich that was handed to her by her Papa. She hadn't eaten anything yet, and she was starving. Lux felt sorry for his baby Slime and fed her five sandwiches, so Eiko would feel satisfied.
