Toz and the cats left Sleepless Brights, hoping that the purple cat would show up eventually.
But aside from a few short moments where the gaze following them vanished, like when they passed through the city gates, there were no signs of the purple cat.
Since the purple cat didn't want to approach them yet, even if they left the city, the group could only be patient. Forcing things by tracking the purple cat down could have the opposite effect, after all.
However, to the group, the purple cat following them even after they left Sleeless Brights and the surrounding areas was a good sign. Although, they couldn't be certain that the purple cat would really follow them beyond the Tumbling Thunder Forest and the Lightning Clouds until that actually happened.
When the group completely escaped the Lightning Clouds' overbearing light and came to the wilderness where darkness existed, the group was finally able to relax their eyes and store away the protective eyewear.
