Walker, Mordant, and Midnight began pulling the shadows closer. They knew that if they ran in to undead mud mantis that they would be facing a harsher challenge. However, they still wanted to do the most that they could to avoid detection.
At the same time, Walker and Gil stayed closer together, this wasn't to hide better but to put their heads together with the wind. The air was all around them. Therefore, the wind elemental mana they could sense was also all around them.
Gil was not adept in sensing it in the same way that Walker was. He had the higher affinity because he was strongly bonded to Zephyr. However, she was not coming out at all. Instead, she had been helping Ventus earlier and still needed to recover. That was the price that came with helping a dragon use massive amounts of wind elemental mana.
