Even though Oli felt nothing lurking nearby, he still didn't completely trust his senses with the storm getting stronger and stronger. Not only was the temperature getting colder by the day and the winds getting worse the closer they got to the shrine, but both factors were gradually ruining Oli's ability to sense the environment. His sensory for earth essence was practically useless by that point, and his only hope came from sensing the darkness of the night. But that was also getting weaker and weaker. So Oli couldn't bring himself to trust his senses for anything further than thirty krin away.
