In the mountain range of Duranberng, the geography of this place is slightly elevated, and with the path they're taking, the mountain will be their home for weeks. Along the way, Theia has been tired from walking.
Her shelter self is not prepared for snow walking, even with Egul casting a mystic shield on the whole party to make walking in now very easy. So half of the time she got a piggyback ride from Heidi.
She wishes he had been fitter, but Hilda said that if she did this every day then naturally she would have better stamina, but not today.
They walk for a whole day to cross the whole mountain. If Hilda was by herself, she'd quickly get lost in this environment. The snow and the tree looked the same no matter where she went. But luckily there was an expert guide who lived in the forest all his life guiding her.
