Spindle!

"We will take turns sleeping, I will take the first shift so you can take a rest," Cain said as he helped the girls prepare a spot to sleep on. They didn't have that much on them to use as bedding, they simply chose a soft spot on the ground and used their bags as pillows.

It was a bit cold down there so they had to sleep close to each other, snuggling together like small kittens. Both Alice and Selena found the strangely warm Sofia to be an irresistible pillow. Cain touched her while she was sleeping to check if she had a fever, she didn't have one, It's just that her body kept its temperature stable even down here. Cain had expected at least her hands to be cold but they were warm.

Watching over the sleeping girls, Cain took his time thinking about what should they do next. Pushing down blindly can get them stuck or potentially facing an unbeatable opponent.
