Lafrenia

Absorbed in her book, Nao spent quite a while in the depths of the caves, ignoring the news that someone had arrived. Eventually, she decided to take a look at the newcomers, but it seems she arrived at an inopportune moment.
First, the girl tried to assess whether it was possible to hide everyone inside (and/or lead them out through another passage, if there was a spare exit from the cave). She hadn't really thought about it before, but it seemed that the security measures were quite simple.
