While Dennings was out collecting firewood with Schmidt, Aydin was preparing fire pit. He dug out a square in the ground and added two small tunnels on the side of it for a proper airflow. He then gathered some grass from the riverbed, dried it in his with the help of his blue-palm-fire, and started filling the bottom of the pit with it. He knew he couldn't start the fire yet anyways because he needed the firewood so he grabbed some incense from his rucksack, put it between his lips and lit the tip with a snap of his fingers.
"Keeps the bugs away," he said to a seemingly curious Sophia. "The lack of monsters is... unnerving. The first time that I'm not feeling like a hunter out here, but rather like prey. We need to be on the lookout if we want to keep the upper hand I guess." Sophia grinned, shook her head and proceeded with putting up her tent.
While the sun was slowly setting, Aydin set down his equipment next to his tent, grabbed his weapon and shield and at down on a log and looked at the river. "I better make some adjustments to my sword while I'm out here," he thought.
While his sword was rather thin while in this form, Aydin could readjust the frame so it was more versatile as a sword. It did sacrifice the ability to switch to spear mode, but it allowed him to combine it with his sharp-edged shield to function as a battleax, almost like some Hunters could do with their "Charge Blades", rare technoswords that stored kinetic energy from attacks to release it in powerful explosions. Aydin's sword was not capable of doing that though, he always wanted to get one of those, but he never could afford one because of their rarity.
When Dennings returned with enough firewood to last through the night, Aydin stacked it in a small square tower in the firepit and lit the dried grass with his flat hand. All he could do now, before exclaiming that he would take first watch tonight, was to start preparing some of the food for the group.
