In her own perception, Audera saw this orb/ball as a bad and potentially evil disrupter. When she noticed that her sense of 'time' was slipping away, she solely blamed the orb, and thought that it was messing with her head.
"I'm barely giving it any mana, how could it even be messing with me?" She thought.
A part of herself urged her to toss this orb into the ocean, but she had to resist. This was an expensive gift, and couldn't be disregarded as any lesser. She didn't want to disappoint the captain either, because he had been nothing but hospitable and helpful so far!
For that matter, she thought. "Gonna keep it for a week, or maybe less? Then I'll toss it in the forest, as soon as we start hiking."
This was the only idea she could think of, which would help her avoid any drama, and she was all up for this alternative. However, she didn't want to stand near this orb either, all for inner-peace's sake. This had a short and effective solution!
